ALERT: Solaris: Process spins/ASM and DB Crash if RAC Instance Is Up For > 248 Days by LMHB with OR

Hello All:

Please take note of this 'ALERT' issue:

DESCRIPTION:

ASM or DB processes may start spinning in a RAC environment after the instance has been running continuously for more than 248 days. This issue only affects Solaris platforms and is due to a faulty C compiler optimization.

The same problem can also affect non-RAC/ASM sessions (in particular if SQLNET.EXPIRE_TIME is used but this is not a requirement to hit the problem)

WORKAROUND:

As a workaround restart the instance every less than 248 days or whenever you hit this problem.

More information on this issue is documented in the following My Oracle Support document:
