[mrtg] MRTG multiple processes

[Pavel Ruzicka]

Hello,

I have troubles, when MRTG have unaccesible more boxes and doesn't end
in 5 minutes interval.

This is output prom ps:

I run MRTG from cron:
*/5 * * * * /usr/local/mrtg/bin/mrtg /usr/local/mrtg/cfg/mrtg.cfg

I know, that MRTG check if there doesn't run concurrent process.
Do you have idea, why this doesn't work?
Or how can I solve it?

I have MRTG 2.16.2 and CENTOS5 distribution of linux.

Best regards,
