Good Morning,
We've been noticing a very high load on our fileserver that holds our
mailman spool. This morning when I ran 2 archivers at once because of
a backlog to a list, I noticed that the stat request volume sky
rocketed.
From strace'ing a second archiver running, I see that the system
doesn't even a tenth of a second in what I assume is the time.sleep
call.
[...]
11:15:10.712914 gettimeofday({1064938510, 712937}, NULL) = 0
11:15:10.712976 gettimeofday({1064938510, 712998}, NULL) = 0
<stat>
11:15:11.512977 gettimeofday({1064938511, 512995}, NULL) = 0
11:15:11.513035 gettimeofday({1064938511, 513051}, NULL) = 0
<stat>
[...]
Now maybe I'm not understanding what the following code is supposed to
do:
def __sleep(self):
interval = random.random() * 2.0 + 0.01
time.sleep(interval)
but I read it to be sleeping for between 0.01 and 2.01 seconds. During
my traces, I never saw it sleep even 0.01 seconds, let alone anything
ressembling something reasonably random.
Am I just missing something?
This was noticed on:
Mailman version: 2.1.2
Python version: 2.2.2
OS version: Solaris 2.8 and RedHat 7.3
Thanks for any help!
NOTE: I'm not on the developers list, but I thought they might have an
answer for this behavior.
Ciao,
