Re: [rules-users] permgen error for simple rule stress test
5.x is in maintenance now, it’s unlikely we will fix this - unless it’s requested by a paying customer. Although we will still consider community provided fixes. If it’s related to the permgen fixes we did for 5.6, it may already be fixed by that. If you can show the issue is still present in 6x, we will try and hunt it down and fix it there.

Re: [rules-users] permgen error for simple rule stress test
Mark, I did some more analysis and I tracked it down to Guvnor my app connects to running out of memory before the test starts failing.Once I restart guvnor and redo my tests I get good response time and it eventually starts to slow down then throw 500 errors.

permien issus were fixed in the 5.6 release, and 6.0 release, by Davide Sottara.

[rules-users] permgen error for simple rule stress test
We are running a simple stress test (whose code I will paste below) for a
numbercompare rule file)
We get the following error before the test finishes. Which seems odd for one
rule
javax.servlet.ServletException: java.lang.OutOfMemoryError: PermGen space
This test is run against 3 loablanced tomcat servers
Here is my JVM_OPTS for each of those tomcat
JVM_OPTS="-Xms4096m -Xmx4096m -XX:NewSize=2048m -XX:PermSize=512m
-XX:MaxPermSize=512m -Xss1024K -XX:+UseCodeCacheFlushing

Here is
I have a simple rule file deployed on guvnor on my abc with JVM_OPTS on the
guvnor being
