Ben, The settings for -XX:PermSize=512m -XX:MaxPermSize=512m seem a bit large based on the max heap size of 1024. Did you run some tuning tests to see that these sizes were needed? I usually see settings on high load servers around 128/192 up-to 192/256. These are all based on the particular

Hello Mark, I was hoping you could help out in this case as well. I have followed this post and made the recommended changes you specified, but still we have periodic CF service restarts. I have attached the VM arguments and evars. Any help in direction would be welcome. Thank you. BEN

I did a talk recently at CFMeetup on CF JVM related matters. You can know what is going on inside CF JVM. Knowing is good it may not be the JVM args that are causing your problems, then you can get on with finding out what really is wrong. Else if the JVM shows it is having GC or memory issues

There are few setting you are missing. -Xms512m This sets the min heap size to the same size as the max heap size. The JVM is designed to auto size up from the min to max as needed however this can lead to problems on occasion. So far the best minds on this subject still recommend
