Answer 1

Hi,
* java.lang.OutOfMemoryError: PermGen space
at java.lang.Class.getDeclaredConstructors0(Native Method)
at java.lang.Class.privateGetDeclaredConstructors(Unknown Source)
at java.lang.Class.getConstructor0(Unknown Source)
at java.lang.Class.getConstructor(Unknown Source)
Solution: Increase the max permgen space -XX:MaxPermSize=256m
There can be a leak in the permgen objects. If tuning parameters do not resolve the issue, we need to use the memory leak detector tools and find out which instances in the permgen space are not getting cleared.
