It sounds like that SUN box is either configured different than the other SUN machines or you have some bad memory modules in it.
Jen -----Original Message----- From: Arunan Kannan [mailto:[EMAIL PROTECTED] Sent: Thursday, July 13, 2006 4:59 AM To: Tomcat Users List; Martin Gainty Subject: Re: Tomcat shutdowns unexpectedly - Please help Hi, Even after making the timeout parameter to 0, still the problem exist. Even I ran a continous polling application in the tomcat and still the problem exist. The tomcat server gets shutdown unexpectedly after some irregular period of time 3 or 4 or 6 hrs. However this problem doesn't exists in other sun machines. Only in a particular system it is occuring. Please help me out to find whats the problem with the system and the tomcat server. Machine Detail: SUN OS 5.8 Tomcat versio: 4.1 Please help. Thanks again.
