Dear,
From time to time I get the following error after executing a select statement:
[SQLCODE: <-400>:<Fatal error occurred>]
[Cache Error: <<UNDEFINED>Main+65^%SYS.DBSRV *%qsc(1187,8)>]
[Location: <ServerLoop>] InterSystems.Data.CacheClient.CacheException [SQLCODE: <-400>:<Fatal error occurred>]
[Cache Error: <<UNDEFINED>Main+65^%SYS.DBSRV *%qsc(1187,8)>]
After repeating the query, the query succeeds.
How do I start debugging this type of issue?
