We have HP SIM installed on Windows 2008 R2. Yesterday it was upgraded from 7.1 to 7.2.
Since the upgrade, System Identification tasks fail for SNMP-based systems. If WMI/WBEM is in use, that works. But SNMP is always reported as not working. This was working immediately prior to the upgrade, so it's not a problem with the remote systems.
If I use Wireshark to look at the SNMP traffic, I can see SIM send out SNMP requests, followed by a valid reply from the device. SIM seems to ignore that reply though, as 5s later it sends out the same request, then gives up after another 5s. (This is the global default 5s wait, 1 retry). The firewall is not running on this server, so it is not that dropping replies.
Any ideas why SNMP responses are not being properly processed? SNMP traps seem to be correctly processed - they are displayed as Events.
I haven't yet found anything in any logs that indicates why it's failing.
