Re: Tomcat shutdowns unexpectedly - Please help
Hi experts, I have found the solution to this problem. The problem is when we start a tomcat in solaris from a user shell (like telnet) , then when the shell quits, the tomcat might get stopped. The bourne shell gives the shutdown signal when the shell quits, to kill the tomcat process. The solution to this problem is we should start/stop tomcat using C-shell. Inside C-shell we need to start the tomcat. At lost, after a good struggle to find this...it seems that it is working (continously) fine now. Please let me know if you have any comments. Thanks all. Thanks to Martin, Cosio, David, Alireza. Thanks to all experts.

Hi Bob, after starting the tomcat using the nohup command , tomcat refuses to stay alive once I logged out of telnet session. it seems that starting inside C shell is only solution in solaris... please let me know your thoughts and suggestions.

Re: Tomcat shutdowns unexpectedly - Please help
Hi Bob, I am sorry. I made some mistakes while adding nohup to start tomcat in my script. Starting tomcat with nohup command is a good solution to this problem. It makes tomcat process immune to SIGHUP as you said. thanks a lot for your help. please let me know your comments. thanks all again, arunan On 7/21/06, Arunan Kannan [EMAIL PROTECTED] wrote: Hi Bob, after starting the tomcat using the nohup command , tomcat refuses to stay alive once I logged out of telnet session. it seems that starting inside C shell is only solution in solaris... please let me know your thoughts and suggestions.

Tomcat shutdowns unexpectedly - Please help
Hi, Please help me in guiding to find out the root cause of this problem. Tomcat Version: jakarta-tomcat-4.1.31 Server OS: SUN OS 5.8 JDK version: j2sdk1.4.2_11 Initially the tomcat server is running perfectly and there is no problem. There is no operation done on the server. Simply it is kept idle. After some 3 or 4 hours the tomcat gets shutdown unexpectedly. This happens repeatedly. Whenever I start the server, after some 3 or 4 hours it gets stopped. There is not enough log to find the cause. I have posted this query in lot of forum and still it is a hard luck. I configured debug=5 in server.xml under conf directory to get maximum log, then also no use. There is no application running in the tomcat server. Simply the when tomcat is started in this SUN server after a few ours it stops always. Please help me. Please let me know if I need to give more information. Thanks in advance, Thanks and Regards, Arunan

Especially true if there is absolutely no logging data just before the process stops. You may have indications of what's happening in other log files like syslog or a core dump file. You may also want to look at bug reports for your OS and JDK. --David Arunan Kannan wrote: Hi, Please help me in guiding to find out the root cause of this problem.
