When this happens and the clients reconnect, they tend to work.  But they won't reconnect by itself until they run into a rather long timeout.  Since the custom full-duplex protocol in its current incarnation doesn't ack any data sent by the client and the latter doesn't expect any regularly incoming requests from the server, this can be days since the client sends its data happily until the kernel's receive queue runs full.  On the server (kernel) side it should be possible to detect stale sockets since the clients send data regularly.
So, assuming my interpretation of this problem is correct, what I wondered was if there is a kernel parameter I can tune which makes the kernel drop/close TCP connections with a RST if they aren't read from by the user space in a timely manner.
Better explanations of what happens here are welcome as well.

A: You can try tuning TCP keepalive to much shorter values. By default a connection can be idle for two hours before keepalive kicks in.
Exactly what values you should use is really dependent on what your application does and what your users expect or how they interact with it.

A: I guess the answer is no.
The problem was solved by replacing the software in question but ideas are still welcome.
The Nissan Terra 2018 price starts at P1,499,000.
Time for your long wait to see the newest SUV of Nissan has finally elapsed. Now, let’s stretch out your arms to welcome the all-new Nissan Terra 2018 landing onto the Philippines.
Nissan Philippines Inc. has officially launched the pickup-based Terra 2018. The SUV is expected to go head to head with the Toyota Fortuner, Mitsubishi Montero Sport, Isuzu MU-X, Ford Everest and Chevy Trailblazer. All of these fierce rivals are armed with a high-tech package, along with muscular and glossy design.
For starters, the Nissan Terra 2018 features a tough yet sophisticated style which perfectly combines elegance and muscle in one body. It boasts a large V-Motion grille, plus boomerang-shaped LED daytime running lamps at the front fascia. As a Navara-based model, the Terra also receives a similar coil spring multi-link rear suspension and ladder-frame chassis, promising a thunderous yet comfortable drive in any terrain.
Stepping inside, the cabin looks familiar with an almost same design as the Navara. It features a sloping dashboard and a V-shaped steering wheel. Besides, the high-level versions of Terra get automatic climate control with a cluster of vents at the rear. The Nissan Terra is capable of housing up 7 people with three seating rows. Entering and getting out the 3rd row has become much easier thanks to an installation of an automatic tumble function for the 2nd one. You just need to push a button placed on the dashboard to move in or out.
Unlike the Chinese-spec version which receives a 2.5L QR25 gasoline mill, the Terra in ASEAN is armed with a 2.5L YD25DDTi turbo-diesel powertrain borrowed from the pickup Navara. All Terra versions’ engines are capable of cranking out 187 hp and 450 Nm of torque, work in a conjunction with a 7-speed automatic or a 6-speed manual transmission.
Similarly to the redesigned X-Trail, the Nissan Terra 2018 can be equipped with series of Intelligent Mobility Features from the carmaker including the Intelligent Rear View Mirror, a 360-degree around-view monitor, rear cross traffic alert, lane departure warning and reverse camera. Additionally, the package also consists of some other features like a slew of airbags, anti-lock brakes, hill-descent control, vehicle dynamic control, tire pressure monitoring system and parking sensors.
According to the latest car news, the all-new Nissan Terra 2018 will get a starting price of P1,499,000.
If you think there isn't going to be another epic crash like the one we had in 2008, wise up. Not only is it coming, it could be far, far worse thank any of us would like. The fact that as of the release of this interview, you still have some time to prepare, may be something of a miracle. Mike Maloney from GoldSilver.com joins me to discuss.You will have the opportunity to work long days, most of it shift work. 12 hours at the post vehicle control checkpoint with no one to relieve you so you can use the latrine. Dumb people that try to get out of anything and everything. "I'm not drunk, why did you pull me over..." You'll get to work the sobriety checkpoint and watch people throw their careers away because they didn't have a plan and dismissed the safety briefing "I didn't get killed in Iraq so I know I'm not going to die while driving intoxicated". At least 3 domestic violence calls every weekend night (even on small posts). All that and the realization that you joined the military to arrest the military. *Actual job satisfaction may vary.Right smack dab in the middle of Europe - civilized, cultured, Europe - Jews are becoming fearful that history might repeat itself.
In Hungary, the third largest political party - the Jobbick party - are protesting the meeting in Budapest of the World Jewish Congress.
It's the usual anti-Semitic crap but coming from what is considered a major party in Hungarian politics, it worries Jews in the country.
WJC spokesman Michael Thaidigsmann said: "We find it a worrying sign that these people express their anti-Semitic and anti-Israeli ideology in such a public way."
Senior figures from the opposition Jobbik party, the third biggest with 43 seats in the 386-member parliament, harangued the crowd with charges that Israeli President Shimon Peres had praised Jews for buying property in Hungary.
They said the WJC had decided to hold its four-yearly gathering in Budapest to shame the Hungarian people.
Conservative Prime Minister Viktor Orban, who is due to address the WJC assembly's opening session on Sunday evening, had ordered the rally to be banned, but a court on Friday ruled police had overstepped their authority in trying to block it.
The WJC, which normally holds its worldwide assembly in Jerusalem, chose Hungary this time to highlight the rise of far-right groups and anti-Semitism in Europe. More than half a million Hungarian Jews were killed in the Holocaust.
"The Israeli conquerors, these investors, should look for another country in the world for themselves because Hungary is not for sale," Jobbik chairman Gabor Vona told the rally near the neo-Gothic parliament along the Danube River.
"Our country has become subjugated to Zionism, it has become a target of colonization while we, the indigenous people, can play only the role of extras," Marton Gyongyosi, a Jobbik member of parliament, told the crowd.
The rally ended after almost two hours and the protesters dispersed without incident.
If "Never Again" is to mean what it says, this kind of fascism must be nipped in the bud while it is weak and vulnerable. Once the scapegoating spreads and becomes popular, the unthinkable becomes thinkable and a nation of decent. cultured people becomes capable of monstrous crimes against humanity.
Europe - and us - may be headed for extraordinarily turbulent times. What is cavalierly dismissed today as hysteria could morph into something sinister. And why not? It's happened before.Press Area: Unboxed!
Transgender in a Gay Museum?
Intervention and Consultation: Zoya.
Unboxed will display these materials in order to interrogate the SMU’s archival practices up to this day. How did these objects arrive here? Who decided that they would be preserved? How does the Museum deal with gaps and invisibilities? Can a museum tell a story without having objects to show? Can archives – places where meaning seems fixed and people come to seek out ‘truths’ – be challenged to accommodate new voices and perspectives? Is it possible to think outside the box of an archive?
