I am using WCS 188.8.131.52 and WLC 184.108.40.206., and SNMP just stopped working last Friday. We had a situation where a user created several hundred ID's, in WCS, then deleted them and created similar ones again, and I think the database may have been corrupted somehow. I have erased the invalid ID's directly on the WLC, and they stay in sync now for new ID's, but the overnight sync, and the config audit both fail with SNMP error messages. SNMP exception while syncing with WLC from the Guest Account Sync task, and Failed for all devices from the config sync. I found the error below in the log, bit I have no idea about how to fix it.
