[fetchmail-users] fetchmail never dies :-(

[Roberto M. <rob...@gm...>]

Hi:

I'm still havin trouble with it. I'm running fetchmail from user's cron.

Even if it's a network problem, I expect fetchmail to die after a
while. But sometimes it doesn't happen.

I've modified the default 600 seconds fetchmail should wait for any
server response to 60 seconds but it still hangs in my process list.

Example pasted (process stopped at 2pm, I found it at 5pm, which means
3 hours without downloading mail!)

someuser   18614  0.0  0.4  2688 1228 ?        Ss   14:00   0:00
/bin/sh -c fetchmail -t 60
someuser   18616  0.0  0.7  4028 1972 ?        S    14:00   0:00 fetchmail -t 60

Any idea of why is this happening? I'm running fetchmail release
6.2.5+NTLM+SDPS+SSL+NLS over Debian Sarge.

Quoting Roberto Meyer:

lsof -p 18616
strace -p 18616

would be a good start.

quite outdated, 6.3.5 is the current one.

Do you have daemon mode enabled? Else see Jakob's reply.

How do you "stop" the process? Did you kill fetchmail or just the
/bin/sh wrapper? 

And if it's "someuser"'s process, how can you be sure it's not been
restarted by cron in the meanwhile?

Even though I consider 6.2.X obsolete and won't fix any bit in it unless
someone tosses $$,$$$.$$ my way, that's not a known failure mode for
fetchmail 6.2.X either. So:

what did you do?
what did you get?
what did you want instead?

Process 893 attached - interrupt to quit
read(3,

And stays there until I type CTRL+C

Sorry, I forgot to answer that for this user I'm redirecting the
stdout and stderr to /dev/null

At the process list the job looks like:

/bin/sh -c fetchmail -s > /dev/null 2>&1

Thanks,

Update to 6.3.6-rc3 and see if it works better for you.

Ok, so fetchmail waits for input from the mail server.
What about your fetchmailrc? Maybe you are using the "idle" keyword.

Well, hope your sleeping by now :-)

Here is the .fetchmailrc of this user:

poll mail.mymailserver.com
       proto imap
       user "som...@so..."
       pass "somepasswd"

That's all... :-|

Thanx for your help,
