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 mor=
ning 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 restarte=
d.  However its response slowing down.  AIX server CPU steadily increases a=
nd approaches 100% after running for 5 or 10 minutes under heavy load..  Se=
eing http process accumulate.  Not seeing much traffic at all in Tomcat ser=
ver 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 tri=
ed 6.0.0.6109.  Recompiled again.  Still no improvement.  Just booted from =
Clone backup taken before the AIX patch and everything  runs fine, no probl=
ems.  Anyone else have this experience with AIX patches/updates?  Not reall=
y much to see in error logs.  Tomcat is configured to run with java6 32 bit=
