Our Sun One Web Server 6.1 SP1 is crashing and restarting my itself. We are running JSP/Servlets which are talking to EJBs on WebSphere Application Server.

After some time we see this error
[01/May/2004:11:43:36] failure (35534): CORE3107: Child process closed admin channel
and the webserver restarts.
Any help?
Thnks

Answer 1

Hi,
Manged to found out the cause of the crash. First the findings. We applied all the patches on AIX required by the IBM jdk. Still the crash was happening. Finally after spending some time digging we managed to find that one of jsp page with this line response.setStatus(HttpServletResponse.SC_CONTINUE); was causing the crash. We need this line for some of the web proxies which dont keep http connection alive. Any ideas.
BTW this same application is running fine on Sun One Webserver 6.0.6 on Solaris.
Thnks,
Jawwad.
