Re: [Resin-interest] Too many open files
I'm assuming this is on Linux or something else that's Unixy. You can find out what your limit for open files is by typing ulimit -a. Here's an example from one of my systems: . Do a man bash and search for ulimit if you want more details. Thanks very much for your help Jose.

[Resin-interest] An interesting memory leak
Here is an interesting one, If I package my application up as a JAR and put it in WEB-INF/lib then I get memory leaks in the perm gen space as none of the Class objects are garbage collected. This is easily re-producable every time. If however I put the application's .class files inside WEB-INF/class and don't bother with the JAR then it will work fine, no memory leaks, runs forever. Any ideas on what I'm doing wrong or if there is some subtle issue with classloaders here that I don't understand ? ___ resin-interest mailing list resin-interest@caucho.com http://maillist.caucho.com/mailman/listinfo/resin-interest
Re: [Resin-interest] resin-interest Digest, Vol 6, Issue 8
If what you describe is really happening, it's gotta be nominated for the Bizzaro Bug of the Month or something. :-) You're sure the perm space is being exhausted? Are you using -XX: +PrintGCDetails or something similar to see the results of gc's on the perm space? Yes of course. and -XX:+TraceClassUnloading so I can see that they do get unloaded when deployed in the classes dir. I'll send you my jar see if it happens on yours too ? ___ resin-interest mailing list resin-interest@caucho.com http://maillist.caucho.com/mailman/listinfo/resin-interest
[Resin-interest] deadlocks
I'm getting this deadlock on my resin servers. does anyone know if I disable logging completely in resin will that stop this happening or will all I do is just stop the outputting to the file ? My servers are crashing daily (at least) so its getting to be a major earbashing issue for me now. Found one Java-level deadlock: = resin-2140: waiting to lock monitor 0x0975151c (object 0x834aff58, a com.caucho.vfs.WriteStream), which is held by resin-tcp-connection-*:80-570 resin-tcp-connection-*:80-570: waiting to lock monitor 0x094d1a8c (object 0x833d7c48, a java.io.PrintStream), which is held by resin-2140 ___ resin-interest mailing list resin-interest@caucho.com http://maillist.caucho.com/mailman/listinfo/resin-interest
