Symptoms

Memory consumption of "rewrite.*" processes is growing constantly. On manually taken core file, result of following command is large (more than 100000). zcat <core-file.gz> | strings -n 15 | grep "^/f5-w-" | wc -l

Impact

Rewrite processes may use all available memory on the box and then cause 'Out of memory' condition and failover.

Conditions

Memory leaks in cases when POST request content could be modified by Portal Access (for example, xml).

Workaround

This issue has no workaround at this time.

Fix Information

Fixed a memory leak of request urls in rewrite plug-in.
