I have a problem with stalling services in my VPS. I use 280Mb RAM and host 5 low traffic domains. I have stalling problems with Postfix, Dovecot, Bind/named and ProFTP. Postfix/Dovecot is the biggest problem since it will email impossible. I am not sure if services get kicked out in times of very high memory use. I disabled already ClamAV, but I like to keep Spamassassin. Any ideas what could it be? Update: I think "munin" could be handy. But it doesn't log anything. I followed this guide: http://www.howtoforge.com/server-monitoring-with-munin-and-monit-on-centos-5.2 Everything installs smooth. I changed the munin.conf Code: [...] dbdir /var/lib/munin [COLOR="Red"]htmldir /home/domain3/public_html/monitoring[/COLOR] logdir /var/log/munin rundir /var/run/munin # Where to look for the HTML templates tmpldir /etc/munin/templates [...] # a simple host tree [localhost] (tried also [COLOR="Red"][www.domain3.com][/COLOR] address 127.0.0.1 use_node_name yes [...] The directory is there and it's 777
Perhaps the HW node you're on is suffering from high disk i/o, that's the most likely reason why services would be staling on a VPS enviroment. Suggest to contact your provider to take a look at that node to check who's hogging resources.
I think my problems are internal. Right now I still work on Munin, with my setup above I get following error: Code: cp: accessing `/home/domain3/public_html/monitoring/': Permission denied cp: accessing `/home/domain3/public_html/monitoring/': Permission denied cp: accessing `/home/domain3/public_html/monitoring/': Permission denied Cannot open /home/domain3/public_html/monitoring/localhost/localhost-cpu.html at /usr/share/munin/munin-html line 488. It seems the [localhost] in the server tree just wants to create a directory "locahost". When I set it to: #[localhost] ...then I get: Code: cp: accessing `/home/domain3/public_html/monitoring/': Permission denied cp: accessing `/home/domain3/public_html/monitoring/': Permission denied cp: accessing `/home/domain3/public_html/monitoring/': Permission denied Cannot open /home/domain3/public_html/monitoring/index.html at /usr/share/munin/munin-html line 488. All directories and files are there, all are 777 and munin:munin Where is the Munin error?

that worked. Thank you! I can access the page now, however, there is no data, I can just see: Overview This page was generated by Munin version 1.2.5 at 2009-02-03 T 02:25:04 That page is now about 24 hours old.
