I noticed something about this on the tomcat 4.0 download site : IMPORTANT NOTE: Virtual machine crashes have been reported when using Linux 2.4 with Sun JVM version 1.2.x and 1.3.x. See the release notes below for more details. (the release notes simply restate this rather useless paragraph)
One would think that would have been somewhat more prominently displayed somewhere, but I never saw it until I went to get 4.0.3 ... We had seen the VM go past Xms before, but it only starts crashing in certain fairly high session situations. I'm working on some tests for jdk1.4.0 and TM 4.0.3 now. If that upgrade fixes this hole, I'll happily post back to the list! I'm glad to hear that I'm not crazy and that others have seen this. -Matthew Laurent F�ral-Pierssens wrote: > Matthew, > > We are using JDK 1.3.1_02.
