[users@httpd] AIX OS Patch Breaks Apache/Tomcat

Hello.

I am running Apache 2.2.29 and Tomcat 7.0.59 with tomcat connector(mod_jk) version 1.2.40 on AIX version 7.1 server.  Started having problems this morning after AIX OS was patched to AIX 7.1 TL 03 SP 04  and openssh to 6.0.0.6108.  WebAdvisor runs fine immediately after apache is started or restarted.  However its response slowing down.  AIX server CPU steadily increases and approaches 100% after running for 5 or 10 minutes under heavy load..  Seeing http process accumulate.  Not seeing much traffic at all in Tomcat server status.  Recompiled apache, tomcat connector, and Tomcat native.  Still no luck.  Later determined there is a bug with openssh 6.0.0.6.108 and tried 6.0.0.6109.  Recompiled again.  Still no improvement.  Just booted from Clone backup taken before the AIX patch and everything  runs fine, no problems.  Anyone else have this experience with AIX patches/updates?  Not really much to see in error logs.  Tomcat is configured to run with java6 32 bit:

IBM J9 VM (build 2.4, JRE 1.6.0 IBM J9 2.4 AIX ppc-32 jvmap3260sr16-20141216_227499 (JIT enabled, AOT enabled)
