Re: AssertException in process_common.c [resurrecting old thread]

[Allen Shaw]

Hi Folks,

Over two months ago I got suggestions from the list on this issue and then failed to follow up.  I'm posting here my followups and the current status, hoping to get some clues on where to go next.

The original post is below, and for refershers the issue is like this:

>> [CDT Oct 14 10:01:37] monit HTTP server started
>> [CDT Oct 14 10:01:37] AssertException: at process/process_common.c:191
>> aborting..

This originally happened with existing version 4.2, and continued even with a fresh build of version 4.4.

Martin suggested it might be race condition and asked to see the .monitrc file.  To be sure, I trimmed the .monitrc down to bare bones -- here it is:

> set logfile /var/log/monit
>
> # freshclam check file
> clam-update.log with path /var/log/clam-update.log if timestamp 5
> hours then exec "/usr/local/bin/freshclam -d -c 6 -l
> /var/log/clam-update.log"
>

With this bare-bones file the error logged is simply one line:
> [CDT Jan 4 13:49:57]
> AssertException: at process/process_common.c:191
> aborting..

Finally, Martin provided through CVS a patch for more verbose error logging.  However, I seem to be having trouble getting past the cvs password prompt. Instructions at http://savannah.nongnu.org/cvs/?group=monit say "When prompted for a password for /anoncvs/, simply press the Enter key." but I may be doing something wrong as pressing Enter just gets me a "Permission denied. Please try again." message and another password prompt.  Hrmm...

Thanks for any help or clues you can offer.
