Help, My Tomcat always down everyday!
Hello, Everybody! My Tomcat always down everyday, I don't know why, and I don't find anything useful in my log files. and when I restart Tomcat, everything will go correctly, but after some time, normally in noon, the tomcat will down again. And another thing is :The memory that jdk occupy increase with time, I don't know whether it is normal or abnormal. Who can tell me several possible reasons about this? I use redhat 6.2,Apache1.3.12, Tomcat3.2.2 and j2sdk1.3.0.04 for linux. The below is my configuration for tomcat, other files is not modified: Tomcat.conf: /// ### # Apache JServ Configuration File # ### # Note: this file should be appended or included into your httpd.conf # Tell Apache on win32 to load the Apache JServ communication module # LoadModule jserv_module modules/ApacheModuleJServ.dll # Tell Apache on Unix to load the Apache JServ communication module # For shared object builds only!!! # @LOAD_OR_NOT@LoadModule jserv_module @LIBEXECDIR@/mod_jserv.so LoadModule jserv_module libexec/mod_jserv.so # Do not edit!

Re: Help, My Tomcat always down everyday!
I've found the Sun JVM 1.3.1 to be unstable on Linux 6.2 and 7.1. Tomcat kept crashing at random intervals (sometime a few days, sometimes a few hours). I switched to the IBM JVM and it started to run OK - no crashing. Maybe you'd like to give that a try.

RE: Help, My Tomcat always down everyday!
Hi Simon, Thanks for the help.I will try that way. In my case ,tomcat is going down everytime exactly after two hours.This happens even if the system is idle.Is there any chance for this to happen due to issues in configuring the tomcat/application.Otherwise ,why it is going down exactly after some particular period.What all could be the possible reasons behind this . I am using tomcat3.2.2,sun solaris 5.8,jdk1.3.

Such like this, when I restart tomcat, JAVA occupy 14M memory, after some times, JAVA occupy 23M or more Memory, do you have this problem? The memory of JAVA increased by time!!! I 'm not familiar with IBM JVM,where can I found IBM JVM? And will it work good with tomcat? will IBM JVM have all functions of JDK JVM? Thanks a lot!

AW: Re: Help, My Tomcat always down everyday!
As long as you don't have used packages com.sun.* there should be no difference between diffent vendors. If you try IBM's and Sun's JDK this is true to more than 99.99 % (as far as we know). What differs are the implementation bugs in the VM or some implementation bugs in the libraries. We have running our application under both VM's and had to change nothing for this. (70K lines of java code + several hundred jsp files) In rare (an unclear) conditions we get core dumps with both of them. Sun's JDK crashes 2 to 3 times less than IBM's in our environment with the given application (We don't use tomcat yet), in an other environments or with other applications the resulty may vary. > -Urspr¨¹ngliche Nachricht- > Von: song yantao [mailto:[EMAIL PROTECTED]] > Gesendet: Mittwoch, 19.
