Re: [Info-ingres] Re: Mutex: ULM Pool (QEF)



Hi Vdohnal,

This could be bug 103157.

Do a trace point qs505, see if it shows any sign of LRU objects
destroyed = non-zero. If it's always zero then you may have this bug.

Hello,
we had similar problems on Solaris/Ingres 2.6 and now we have it back
again on Linux 64bit/Ingres 2006. And we have about 150 concurrent
users.

Our problem is in QSF memory. If the QSF memory is filled up more than
30%, everything goes very slowly. But unix has idle over 80%. And our
workaround is run trace point qs506 every few hours.

On Solaris two times during 2 years trace point qs506 crashed DBMS
server and our production db was inconsistent.
