Question
I have three Windows Server 2003 with 2 GB RAM.
- Server1 tomcat 5.5.25 jvm version SUN 1.6.0_11-b03
- Server2 tomcat 5.5.25 jvm version SUN 1.6.0_14-b08
- Server3 tomcat 6.0.18 jvm version SUN 1.6.0_14-b08
For the three servers JVM parameters are:
-XX:MaxPermSize=256m
-Dcatalina.base=C:\Apache Group\apache-tomcat-5.5.25
-Dcatalina.home=C:\Apache Group\apache-tomcat-5.5.25
-Djava.endorsed.dirs=C:\Apache Group\apache-tomcat-5.5.25\common\endorsed
-Djava.io.tmpdir=C:\Apache Group\apache-tomcat-5.5.25\temp vfprintf
-Xms512m
-Xmx1024m
For some months everithing worked fine. Last friday we installed some windows updates. After the reboot tomcat doesn't start anymore, with error:
Error occurred during initialization of VM
Could not reserve enough space for object heap
We reduced the parameter -Xmx1024m to -Xmx768m and now tomcat starts. But we need greater max heap size What happened to our servers ? Thanks in advance.
Solution 2
Finally found it!!! The update KB956572 makes Tomcat crash if you specify more than 768M heap size in JVM aprameters. It's a killer update for Tomcat based web servers!
