Right, you don't need a lot of load to see this problem arise over time. Because the connections aren't cleaning themselves up, they're compiling over time.
Do a 'netstat -an|grep <your ajp13 port #>|wc -l', and see if it only increases over time. If it is not going down, than it most likely is the problem as described below. >Since JK 1.2.0, cache_timeout and socket_timeout properties as been >added to close connections after some time of inactivity, for more >informations refer to Workers HowTo ." -----Original Message----- From: John Gentilin [mailto:[EMAIL PROTECTED] Sent: Tuesday, September 14, 2004 2:30 PM To: Tomcat Users List Subject: Re: Help, Tomcat 4.1.30, Linux Stops responding after 24-48 hours The funny thing is there is no load on this server, maybe 100 hits/day go to the web application and maybe 10K hits/day to the Web server by itself. Another piece of the puzzle is that when Tomcat stops handling requests; I try to stop Tomcat with catalins.sh, it reports a success the first time, and no socket on subsequent tries as it should, but the process is still in my process list and needs to be removed with a kill -9 After that if I run Tomcat again, without restarting anything else the system runs just fine Tran, John wrote: >Are you using mod_jk? > >http://jakarta.apache.org/tomcat/connectors-doc/jk2/faq.html > >This *might* apply: > >"Under heavy load, I've got many threads in Tomcat even if my Apache Web >Server handle much of the load > >Under heavy load, Apache WebServer create many childs to handle the >load, which will in turn create many connections to Tomcat to forward >the requests they should handle.
