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

[Martin Pala]

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
