Subject unable to set MaxPermSize past 128MB
Date Mon, 06 Feb 2012 03:44:03 GMT
Hey one more wild question for this sunday evening (I hope)

I just upgraded to 6.0.35 running on Win2K3 32 bit platform.  I used the
Win installer.  I tried setting the Initial Pool to 512MB and the MaxPool
to 1536MB of ram, however when I pass in the -XX:MaxPermSize:256m in the
config -> Java -> Java Options section, Tomcat appears to start in the
services, but the monitor shows that the service is not started.

Also in the log: 2012-02-05 21:08:40 Commons Daemon procrun stdout
Error occurred during initialization of VM - Could not reserve enough space
for object heap

However when I bring the MaxPermSize down to 128m, It initializes just
fine.  Obviously I'm missing something here.  Any insight?  I'd like to
increase the MPS parameter to either 256 or 368m.  Thanks in advance as

- Josh
