Not if you were able to restore from your backup. It might have been an
index balance problem but backup/restore should have fixed that.

Did you change something?

If so, the first step would be to find it. Drop a TIB_MonitorDialog into
the app and watch the parameters that get passed just before the anomaly
occurs. Note the PK value of the rows that seem to cause the problem and
look at them in the Cursor table of IB_SQL.

Other than bad data, what's the environment? For example, are you using a
Win local connection? It could be a memory capacity problem, or a race
condition, that has arisen due to table growth...if you are using a local
connection, try changing to local loopback - use the localhost server and
set the Protocol to cpTCP_IP.

Apart from that, no ideas absent further clues.
