Subject: [Exim] Exim 3.22 leaking file handles?
Hello,

I have problems with Exim 3.22 which seems to leak
file handles on two Linux machines:
#1: SuSE Linux 6.2, Kernel 2.2.18, glibc 2.1.1, 
    one IDE disk
#2: SuSE Linux 6.4, Kernel 2.2.16 + raid patches, 
    glibc 2.1.3, two SCSI disks as software RAID.


Under heavy load, both machines seem to run out of
available file descriptors, no processes can run anymore
because of that.

One error message of exim itself:
2001-04-19 11:37:15 14qAsF-0000V4-01 exec of 
    exim -Mc failed: Too many open files in system


I tried raising /proc/sys/fs/file-max to 16384
and /proc/sys/fs/inode-max to 24576 on machine #1
but that didn't help.

Any ideas?

Thanks,

Florian
