Re: Too many open files, again

I am (for the most part) using the IBM Java 1.4.1 kit on Linux (Mandrake
9.1). I have not tested this particular aspect on Windows.

The application had died this morning with the same problem, so I had to
restart it. Here is the result of running the cat command:

Before restarting

[sfcrm@demo sfcrm]$ cat /proc/sys/fs/file-nr
2076    90      52422



After restarting:

[root@demo sfcrm]# cat /proc/sys/fs/file-nr
2128    822     52422


I would be grateful for any ideas/patches/workarounds.

Thanks and regards.
