unbound_munin_hits-day

Some times munin-1.2.6 (on server with Ubibntu 8.10) not fetch unbound statistics from munin-node-1.2.6 and unbound 1.2.1 (on server with FreeBSD 7.1).

/var/log/munin-node.log:
2009/04/10-09:20:05 CONNECT TCP Peer: "xx.xx.xx.88:54260" Local: "xx.xx.xx.90:4949"
2009/04/10-09:20:18 Plugin timeout: unbound_munin_memory : Interrupted system call

 (pid 73420)
2009/04/10-09:20:42 Plugin timeout: unbound_munin_queue : Interrupted system call
 (pid 75055)

After remove state and lock file, fetch stats work again.
rm -r /usr/local/var/munin/plugin-state/unbound-state*

Graph hits for example attached.

Looks like the lock file was not deleted by one of the earlier munin lookups.  But it should have, perhaps it crashed or the machine was rebooted? Did this happen right after a reboot?

Thanks for the logs,

Fix in svn trunk r1596.  Fix removes stale lockfiles.

Thank you for your report,
