Hey, my name is David an I'm working for a electronic consumer company in Germany we are selling and producing TV's, receiver, satellite dishes etc..
We got some serious trouble with our tomcats. Basically we using two 7.0.12 tomcats on a single Debian 6.0. One is running on port 7090 and the other on 9080. Time after time both tomcats are crashing. I found too many open files in tomcatlogfiles. Both Servers are running with one user (TOMCAT). After changing max open files for that particular user I was able to get more than 1024 open files. Currently I'm checking log files every few minutes. With lsof|grep tomcat|wc -l I'm counting the open files by user. Usually there are around 600-700 open files. But sometimes the count grows and we have more than 1200 open files. When ever the server does have so many open files I checked: lsof -u tomcat an figured out there are many connection waiting to be closed. The connections are looking like this: java 22312 tomcat 153u IPv6 1508517 0t0 TCP localhost:afs3-rmtsys->localhost:50127 (CLOSE_WAIT) I googled a bit for afs3-rmtsys and figured out that the protocol seems to be a remote cache manager. But I couldn't find any more information. Does anyone of you know what my problem might be? Thanks! Mit freundlichen Grüßen David Kumar Softwareentwickler, B. Sc.
