Description

under certain circumstances, too many files are opened and the JVM gives back the following error: FileNotFoundException: "Too many open files"
at the moment I have been able it to reproduce with high load or stop james with many mails in spoolqueue and start again

I have been able to see the files that erase of the Spool directory, but they are not closed, can who Mr. Garbage Collector does not release the objects, I have proven to call System.gc(), this workarround works, but the speed is bad.
Another workarround is set SpoolManager Threads to 1 but is the same speed (turtle).
