Subject: record STAT = SCAN

EPICS folks,

I have a record connected to hardware through device support that I have written. I have a situation in which the record ends up in the state STAT = SCAN, SEVR = INVALID

I looked in dbAccess.c and it appears to me that this can mean that MAX_LOCK requests were made to process an already processing record. Is this correct?

I am guessing my device support is not finishing properly so that consecutive requests pile up. Is this a good guess?

Apologies for the open ended nature of this query. Searching for "STAT"  and "SCAN" can find a lot of not particularly helpful info.

Regards,
