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.

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: # ulimit -a core file size (blocks, -c) 0 data seg size (kbytes, -d) unlimited max nice(-e) 0 file size (blocks, -f) unlimited pending signals (-i) 131072 max locked memory (kbytes, -l) 32 max memory size (kbytes, -m) unlimited open files (-n) 1024 pipe size(512 bytes, -p) 8 POSIX message queues (bytes, -q) 819200 max rt priority (-r) 0 stack size (kbytes, -s) 8192 cpu time (seconds, -t) unlimited max user processes (-u) 131072 virtual memory (kbytes, -v) unlimited file locks (-x) unlimited As you can see, the default limit for open files is 1024. You can set this for your session uing ulimit like this: ulimit -n 1. To make it sticky across reboots you'll have to edit /etc/security/limits.conf and add a line that reads something like this: resin hardnofile 1 Do a man bash and search for ulimit if you want more details.

How is that .jar configured in the resin.conf? Can you give the class-loader section of the resin.conf that references it?

Additional information( if it helps ): wtcls.jar is our own code. it is symlinked to resin_home/lib/local/ wtcls.jar If we remove the symlink, resin will do the same thing, but with a different jar file( in this case, wicket.jar, from the wicket project ) Any help solving this problem would be appreciated, thanks. - Dave ___ resin-interest mailing list resin-interest@caucho.com http://maillist.caucho.com/mailman/listinfo/resin-interest ___ resin-interest mailing list resin-interest@caucho.com http://maillist.caucho.com/mailman/listinfo/resin-interest
