one of our devmon servers turned purple this morning. It stopped here:

[09-01-09@07:24:36] DEBUG TEMPLATES: running post_template_load()
[09-01-09@07:24:36] DEBUG CFG: running read_hosts
[09-01-09@07:24:36] DEBUG SNMP: running poll_devices()
[09-01-09@07:24:36] Starting snmp queries
[09-01-09@07:24:36] Getting device status from hobbit at xx.xx.xx.xx:1984

It is possible, that this system couldn't reach the hobbit server
at that time. However it didn't recover from this status.

The debug log shows some messages like 'Use of uninitialized value in addition
(+) at (eval 94189069) line 1, <$__ANONIO__> line 1450529.', too. But they are
shown in every cycle and not just before devmon stopped.

Best regards
Thomas
