James File Repository Error: Too many open files
------------------------------------------------
Key: JAMES-612
URL: http://issues.apache.org/jira/browse/JAMES-612
Project: James
Issue Type: Bug
Components: MailStore & MailRepository
Affects Versions: 2.3.0rc1
Environment: james 2.3.0rc1, java 1.5, linux
Reporter: Guillermo Grandes
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).
