JVM memory initializazion error after windows update
- by gianni
We 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:\Programmi\Apache Group\apache-tomcat-5.5.25
-Dcatalina.home=C:\Programmi\Apache Group\apache-tomcat-5.5.25
-Djava.endorsed.dirs=C:\Programmi\Apache Group\apache-tomcat-5.5.25\common\endorsed
-Djava.io.tmpdir=C:\Programmi\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 doesnt start 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.
