title: EOutOfRessources on CreateForm
body: <p>I have a strange problem: My Delphi application raises an EOutOfRessources exception just after starting up on a Application.CreateForm call. Is somebody out there, who solved such a problem?</p>
  
  <p>The strange things are</p>
  
  <ul>
  <li>that this happens on a single machine only. I do not have this
  problem on other computers </li>
  <li>that the application runs properly, if a teleservice is active (we use Danware NetOP). If teleservice is not running (Netop waits for a guest log in), the application fails.</li>
  </ul>
  
  <p>The application was developed under D7; OS is WinXP SP3.</p>
  
  <p>Thanks for your help</p>
  
  <p>--- Update 1 ---</p>
  
  <p>Application uses EurekaLog to catch exceptions and to store error information. It says, the EOutOfRessources happens on Application.CreateForm (some 50 forms already created, a few other forms pending to create), the message is "out of system ressources". Exception address is 7C81EB2E.</p>
  
  <p>The EurekaLog also provides the call stack :</p>

  <p>Total memory use is about 60 MB; the application has some 20 MB in use. </p>
  
  <p>I do not know the used number of handles; EurekaLog does not provide this. </p>
  
  <p>--- Update 2 ---</p>
  
  <p>Now we exchanged the PC by another one of same type. The exception did not raise again. However, we had a similar effect on another machine, now not being able to open a file during Application.CreateForm. The file name string was empty ... After a number of poor people resets (power shut down) the problem disappeared.</p>
  
  <p>We suspect, that the exceptions are caused by a network problem. At this customer, we have four applications running (per two identical projects). They share data over a company network; for that there is a NAS. Network login is done with Windows start up, about 2 minutes before starting the applications. 
  Teleservice runs over company network too. </p>
  
  <p>The question is now, if Application.CreateForm is trying to get connected to network. Our OnCreate event handlers do not require an open network. 
  The applications' source code is on the NAS too (encrypted by TrueCrypt). After compilation we copy the EXE and all other needed files to a local hard drive and run the application from that place. Normally, the TrueCrypt container is closed.
  Could it happen, that the EXE is searching for some files on NAS resp. the TrueCrypt container?</p>
  
  <p>Maybe, somebody is familiar with such issues. Thanks for your help.</p>
