One day i found these in my logs, and the vacuum process hung, effectively
locking everybody out of some tables...
Version 7.1.2

VACUUM  ANALYZE
NOTICE:  RegisterSharedInvalid: SI buffer overflow
NOTICE:  InvalidateSharedInvalid: cache state reset

It was sleeping in semop().

Any ideas, or fixes is welcome...

cheers

Magnus
