Description fdragon 1999-06-02 19:57:23 UTC 
When this is read by snmpd to report stats for mrtg, snmpd
will die. This is install of RedHat 6.0, with addition of
mrtg, MySQL, and some perl libraries all in RPM format.

This makes it hard to use SNMP to monitor the machines.

Comment 1 Jeff Johnson 1999-06-05 16:35:59 UTC 
I'm changing this component to ucd-snmp because that's where
the fix will be.

The easiest workaround is to rebooot the machine in order to reset
the counters that are causing the snmpd segfault. There may also
be a more precise way (than renbooting) to reset the ethernet
counters.

Comment 2 eric 1999-06-11 19:42:59 UTC 
Fixed in the ucd-snmp 3.6.2 release. The snmp daemon now rolls over
rather than core dumps when the size of the traffic counter exceeds 32
bits. MRTG has no problem with that happening, though its counts may
be off for the 5 minutes where the rollover happened. I have 3.6.2
RPM's at ftp://ftp.estinc.com/pub/unsupported and will upload them to
a Red Hat incoming site as soon as someone tells me how.
