UIM snmpgtw probe stopped sending traps

Issue/Introduction:

The UIM snmpgtw probe was working fine and then after a restart stopped sending traps.

The log has:
Jul 7 13:38:11:496 snmpgtw: RREPLY: status=not found(4) <-10.XX.XX.XXX/48002 h=37 d=0
Jul 7 13:38:11:496 snmpgtw: attach failed 4(not found), trying subscribe.

Jul 9 10:56:49:435 snmpgtw: disconnected from hub

Cause:

The message 'attach failed 4(not found), trying subscribe.' indicates the probe failed to create and attach to its queue.

Environment:

Release:
Component: UIMSGW

Resolution:

To help ensure the probe always connects to its queue a permanent queue can be created.
Open the hub configure GUI
Queues tab > New
Name = snmpgtw
Type = attach
Subject = alarm

It is recommended to use the latest robot and hub updates.

Additional Information:

By default the snmpgtw probe will create a temp queue each time it is activated. The queue name will be t_<next available number>.

If a queue is created with the name snmpgtw, the probe will use that rather than creating a temp queue.
