Hello,
During capacity tests we've received permGen OOM exception. The
occupied space in the permGen area increases rapidly. Any opinions?

In our project we are creating a StatefulRuleSession and
saving it in a per-thread context (i.e. Each thread has it's
own StatefulRuleSession):
ruleServiceProvider.getRuleRuntime().createRuleSession(contextName,
properties, RuleRuntime.STATEFUL_SESSION_TYPE);
When a thread session ends, we are calling release on the
previously created StatefulRuleSession.
Changing the following lines:
public abstract class AbstractHashTable
...
public Iterator iterator() {
// if ( this.iterator == null ) {
// this.iterator = new HashTableIterator( this );
// }
//
// this.iterator.reset();
// return this.iterator;
HashTableIterator iterator = new HashTableIterator(this);
iterator.reset();
return iterator;
}
Seems to solve the problem I've encountered. What's your opinion?

a working memory should be single threaded, so not sure
how this could be a race condition?

I've done a little debugging. The code fails in the
following segment:
public static class HashTableIterator
...
while ( this.entry == null ) {
this.row++;
if ( this.row == this.length ) {
return null;
}
this.entry = this.table[this.row];
*// ---> index out of bounds exception*
}
}
this.row has the same value as this.length despite the
condition above it. Probably a race condition issue.

Not really :(
In your situation I tend to keep removing rules and
data while still making sure the error happens, to
get it down to a minimum. Please do try, as this
isn't an error that should happen. Or alterntaively
you can open drools-core and drools-compiler in
eclipse and execuse and debug this yourself - in
your situation this might best. you can put in a
breakpoint to listen for that particular exception.

It's hard for me to provide a self contained
project. The drl is long and uses several business
objects. It's the same drl as we've been using for
306 minus the keyword changes.
Is there anything else i can check or provide you
in order to solve this matter.
Thanks

Can you provide us a self contained project
which creates this error? Unless we can
recreate it, it will be very hard to track it
down. Please attach the project to a jira and
we'll make it a priority.

Hello,
I've just started integrating MR3 into my
project (I've previously used 3.06). The
drl compiles and everything seems fine, but
during
tests the following exception is thrown for
time to time:

This only happens during high load tests.
Can anyone help me?
Thanks
