Hi all,

I have JSF project in Sun Java Studio Creator 2 Update 1 and Sun Application
Server 8.2 PE and Oracle 10g EE.
About 100 active users per day.

There are two default http-listeners working on AppServer.
http-listener-1 (29080 port) and http-listener-2 (secure) (22043 port)
All server and listeners settings set to default.

Problem:

I have unstable but offten problem with http-requests to working http-listener
(http-listener-2 for example). It is stopping and  doesn't send any
http-response. Working http-listener have not any reaction to any http-requiests
(including requests to another contexts). 
<<server.log>> has not any info about it.

This problem resolvs only by restarting AppServer.

Thanks

P.S. Migration to other version Of JEE Server impossible (or hard). 

P.P.S. Sometimes server.log contents stack trace:
