Your memory needs are quire modest, so a 32-bit JVM should suffice. I think you mentioned that, in the past, on lesser hardware, a 32-bit JVM was being used. > The failures look a lot like the linux OOM killer (which Mark or Chris > said way back at the beginning which is now 2-3 months ago.) While the Linux OOM killer /is/ possible, I agree with Chuck that it's sounding less like a memory problem. I would have bet on a hardware problem, but memtest86 seems to have ruled that out (any x86 system I've suspected of having flaky hardware has always failed on it's first round of memtest86 testing). I wonder if there's a memtest_x64 that you should be trying, instead <shrug>. I honestly can't think of any other reason why Tomcat would be just dying with no trace: a clean shutdown would produce logs. The Linux OOM killer would say something in the system logs (you're not doing remote syslogging, and the message is somehow getting lost, are you?). A JVM bug would likely generate an hs_pid.log file with details of the crash. I have to admit, I'm stumped. :( - -chris -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.10 (MingW32) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iEYEARECAAYFAkt1cAcACgkQ9CaO5/Lv0PB6lgCfc2s6FpRt+LNqzgNV2KG76FiZ VeQAn3utd641tdOet+lQkG+QjpUg/txt =QLU+ -----END PGP SIGNATURE----- --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
