Hi all,
This is kind of late, but I can tell you that the delack-timer-5 patch
mentioned below (which has been included in 2.2.15pre1 and above, I
believe) has solved my long-standing problem of the crashing webserver
(both Apache and Mathopd) locking up the whole machine on 2.2.x.
The webserver in question has been up for 7 days non-stop (used to reach
maximum 2 days), and the only problem I had with a stock 2.2.14 and the
delack-timer-5 patch was that every now and then a process (not always the
same) got stuck and became unkillable, causing a load of 1 for each stuck
process. I rebooted the machine with 2 stuck processes after 7 days, and
now it has been up for another 5 days, no stuck processes yet.
Hope this helps,
Ward.
