Thanks guys for all the feedback. I have tried the following suggested tasks:
- Upgrading Tomcat to the newest 7.0.55 on all our servers -> Problem still persists - Force a System.gc() when connection count is on the loose -> Connection count is not dropping - Lowering the log level of NioEndpoint class that contains the Poller code -> No info about why the poller thread exits in any tomcat logs - Reverting the JVM stack size per thread to the default is discussed previously -> Problem still persists I have now checked out the NioEndpoint source code and recompiled it with a logging try-catch surrounding the whole of the Poller.run() implementation as I noticed that the outer try-catch here only catches OOME. I will report back with my findings as soon as the problem arises again. /Lars On Fri, Jun 27, 2014 at 9:02 PM, Christopher Schultz < ch...@christopherschultz.net> wrote: > -----BEGIN PGP SIGNED MESSAGE----- > Hash: SHA256 > > Filip, > > On 6/27/14, 11:36 AM, Filip Hanik wrote: > > Are there any log entries that would indicate that the poller > > thread has died?
