Solve this problem

Reference:

Maxpermsize:
The permanent space is memory allocated outside the regular
Heap (I. e. In addition to the-xmx setting), so it is important
To ensure there is enough physical RAM on the machine.
The permanent space is used to primarily store classes and
Objects Created for reflection support (methods etc.). If
You have a large number of classes in a Java application,
An OOM can occur if the permsize is too small.

From one of your previous posts, you seem to have 8 applications,
So yes, setting the permsize and/or maxpermsize cocould help.
Also, 256 MB sounds small for a server with 8 applications.
The OOM cocould simply indicate that your heap is too small.
Hope this helps,
