Cacti not remembering SNMP items

[BSOD2600]

I've noticed lately, that Cacti is not remembering items in Associated Data Queries. It always says Success [0 Items, 0 Rows]. Graphs continue to work, but there is something wrong...

Same goes with a script I have which keeps track of the number of processes and only reindexes if there is a change. It always is saying the previous count was 0.

Any ideas... TheWitness?

Fixed.

Looks like my cacti.host_snmp_cache table was corrupted. Had to repair the mysql database and reindex all SNMP queries.
