I have Airwave poiting at various wism2s. 6 of these run 7.4.122 code and are working perfectly well, but we have another HA pair (wism8) running 8.0.100 that is less good. We recently upgraded Airwave from 8.0.0 to 8.0.4, then a few days later wism8 suddenly seemed to go down according to airwave, along with all it's APs. It is actually still up, and so are it's APs. When I try to SNMP poll wism8 from the Airwave GUI, it eventually times out with nothing interesting appearing in the event log. If I try to snmpwalk from the Airwave server CLI it works perfectly well.
Any idea in which logs might be some useful information or where to start troubleshooting this?
