I'm running Munin on Debian Lenny. When I'd noticed that I'm receiving its reports too rare, I went to the server today (Aug, 22) and found there a thousand of processes like this:
root 32064 1536 0 Jun30 ? 00:00:00 /USR/SBIN/CRON
munin 32067 32064 0 Jun30 ? 00:00:00 /bin/sh -c if [ -x /usr/bin/munin-cron ]; then /usr/bin/munin-cron; fi
munin 32068 32067 0 Jun30 ? 00:00:00 /bin/sh /usr/bin/munin-cron
munin 32250 32068 0 Jun30 ? 00:00:00 /usr/bin/perl /usr/share/munin/munin-limits
munin 32251 32250 0 Jun30 ? 00:00:00 mail -s Munin notification my-address@at-another-server.com
So, where's could be the problem? In Munin or in MTA (Postfix)?
The problem is not permanent. Some of the emails were received.
