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

[Allen Shaw]

Hi Martin,

Thanks for the link and the quick response.  I compiled and installed monit-4.5-cvs20050106, and it runs like a charm, no problems.  Running verbose I get the output shown below.  Just to check my sanity I went back and ran monit-4.4, and the same error returns.  Looks like the version you sent me avoids the problem, but it would be good to know what the problem was, wouldn't it.  Please let me know if I can do some more testing for you on this machine.

Thanks,
Allen

Hi,

i have tested it but it works on my station (debian 3.1) without problems.

I have tried following configuration:

--8<--
set daemon 5
set logfile /var/log/monit
check file slapd_rc path /etc/init.d/slapd
  if timestamp > 5 hours then exec "/bin/echo"
--8<--

within following tests:

1.) compile monit-4.4 on system running kernel 2.4.27, then test it on system running kernel 2.4.27
status: OK

2.) compile monit-4.4 on system running kernel 2.4.27, then test it on system running kernel 2.6.10
status: OK

3.) compile monit-4.4 on system running kernel 2.6.10, then test it on system running kernel 2.6.10
status: OK

Then i tried the same tests with actual cvs version of monit - again without problems. It seems that the problem depends on some special condition which i'm not able to recreate.

I have created cvs snapshot of current monit version for you - you can find it here:
http://www.tildeslash.com/monit/dist/snapshot/monit-4.5-cvs20050106.tar.gz

Please compile it and try to run with verbose option (-v). You can also use -I option to run monit in the foreground (you will see messages directly on console).


Thanks,
Martin
