Hi Gurus,

I see following messages almost every 5/10 min. in PMON trace file of the PROD database. I recently upgraded the database to 8.1.7.4.11 from 8.1.7.3.0.

Has anybody seen these errors before? Could somebody help me understand the cause and implications of these messages?

Pl. note that there is no "Latch free" or any SGA wait events in v$session_wait.
