Hi
I'm running Red Hat 7.3 on n i586 with 64Mb ram. I have a dial up connection and use sendmail as my MTA with fetchmail picking up mail from my ISP.
My basic fetchmail config is of the form:

poll x.x.x.x proto pop3
user john with pass password is john here

Of late fetchmail has been terminating randomly with signal 15. It can terminate after 20 minutes, or even after 1 minute and I can find no apparent cause for this.

Does anyone have any idea on the most common causes of signal 15 terminations?

Just to add on, the fetchmail man page has, under the description of exit codes:

15 Server timed out during an IMAP IDLE.

Is this my server or the ISPs server from which I'm collecting mail which is timing out? And I'm specificly using POP3 in my configuration so why is this applying to me?
