Actual Behavior
Experiencing High-Memory Usage and Swapping.

With BI Publisher 11.1.1.7.0 (Build 130303.2025 64-bit) on RHEL Linux 6.4, experiencing consistently high-memory usage and swapping throughout all environments.
It appears to be a memory leak in that a reboot temporarily resolves the problem, but within a few weeks it will gradually increase until swap is maxed out (nqsserver process being the culprit).
This is regardless of whether the product is handling any requests.

Have allocated the recommended 8GB of RAM for each server and have tested with different heap sizes, but the result is the same.  Also tried doing a fresh (standalone) install of the product, but the issue still persists.

Changes

 None.
