Perm Gen issue in drools 6.1.0.Final

[Vivek Hingorani]

While loading rules the application is throwing perm gen memory space error , with 512 MB of perm gen space.

The same application is running fine when run on drools 5.3.0.Final version . Is there any issue with drools 6 for loading the rules?

Anyone who has worked on drools 6 has faced this problem? Any replies would be helpful

It's possible. Since you did change major versions of Drools, why not bump PermGen up to 768 and see if it helps?

Or try running under Java 8, which supposedly doesn't use PermGen any more and therefore shouldn't have the problem at all.

Thanks for the reply Tim. We need to stick with java 7 and to increase perm gen there are a lot of approvals required and hence was looking for a solution in case we can do things differently. Any help will be much appreciated
