Anyone seeing odd crashes on Lucent PM3's tonight? We have boxes dying all over the network with hard lockups. The machines are in different physical locations with different telcos. It smells alot like a DOS of some sort.
For some odd reason, both of our NYC POPs with different CLECS in different locations had the same problem periodically with different random PM3s. We now block all SNMP from all addresses except our management networks toward our PM3s and they have been fine ever since. You will need to create an outbound Ethernet filter from your router or an inbound filter on the PM3 Ethernet or WAN for this. Just in case the bug would still show with an inbound filter, I suggest you filter on a non-PM3 box if possible. We run ComOS 3.9.1b1 if it is of any consequence.
