Hi,
Getting "cannot create trap2sink" error (for unix socket), during snmpd
initialization.
Following is the /etc/snmp/snmpd.conf file content.

There is no permission issue for this particular socket on few setups only and
there is no difference in installed software on both the setups.
And this issue we are seeing in only cloud environment.

I'm able to create unix socket with the same name. Tested it using simple unix
socket client/server application.
Any pointers to debug this? What could be the issue here?

Varun
