hi chris Thanks for ur rely.
The heap is before the 'crash' Before I posted I've already checked all the log files. These is no any errors in stdout neither stderr, the service was running normally, which is strange to me, and that's why I suppose it's the crash of jvm. But there no such file as hs_err_pid30854.log. We run the service with Tomcat5.5+mod_jk+Apache 2 on a virtual machine (with 512m memory), the tomcat is gone, but apache remain. Here is the config for jvm java.exe=/opt/local/java/bin/java tomcat.home=/opt/local/apache-tomcat-5.5.25 java.classpath.file=/MIDDLE/SESAM-Vitale/ poc-bi.gie-sesamvitale.net/tomcat1/conf/classpath.txt java.args=-Xms128m -Xmx512m -Dnetworkaddress.cache.ttl=300 optimizeit.enable=false optimizeit.hotspot=false On Thu, Jul 30, 2009 at 6:08 PM, Christopher Schultz < ch...@christopherschultz.net> wrote: > -----BEGIN PGP SIGNED MESSAGE----- > Hash: SHA1 > > Chun, > > On 7/30/2009 11:13 AM, Lin Chun wrote: > > I got a problem.
