[HACKERS] Notice and share memory corruption

[Hannu Krosing]

I get the following on untuned Linux (Redhat 6.2) using stock 7.0.2
rpm-s

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

Actually I get many of them ;(

I'm running a script that does a bunch of mixed INSERTS, UPDATES,
DELETES and SELECTS.

after getting that I'm unable to vacuum database until I reset the OS

Where/how should I start looking (or is it a known problem)

Are there any simple workarounds to stop it happening.
