Description Jani Ollikainen 2003-11-17 14:49:30 UTC

Description of problem:
After updating to fedora core I got emails that told i'm running 
parallel instances of mrtg. I look and look where the problem could 
be. Didn't find. Only line of mrtg which i had was in /etc/crontab

0-59/5 * * * *  root  /usr/bin/mrtg /etc/mrtg/mrtg.cfg

Then I replaced that mrtg bin with shellscript that did

logger mrtg: $@
ps auxwf

Got only 1 email, but noticed two mrtg's running in ps output and
two identical lines in /var/log/messages .. hitting head to the wall 
and thinking.. then i tried with

*/5 * * * *  root  /usr/bin/mrtg /etc/mrtg/mrtg.cfg

and got only one email and line in messages. So wtf?
Altered that back to 0-59/5 and got 1 email, 2 lines in messages.

So there has to be some weird bug in new vixie-cron which cannot 
handle that 0-59/5 right, which should be correct syntax.

Umm, it seems that it does it with */5 sometimes.. weird..




Version-Release number of selected component (if applicable):
3.0.1-76

How reproducible:
Didn't try
