title: Application crashes, but no core dump generated
body: <p>I have an issue where my application keeps on dumping core after few day/weeks, but unfortunately, generates no core dump. </p>
  
  <p>We tried to set <code>ulimit -c unlimited</code> with no success, so we incorporated <code>setrlimit</code> functionality in the code itself, but had no luck with that approach either. And, on top of that, we added MALLOC_CHECK_ too. </p>
  
  <p>Interestingly, when we tried to initiate a manual core dump (using <code>kill -ABRT &lt;pid&gt;</code>), it did generate a core dump.</p>
  
  <p>I could see the following message in <code>/var/log/message</code></p>

  <p>Any suggestions on how to make the application generate core dumps more reliably? </p>
