Hi,

I am using Cent OS 6 () and Postgresql 9.0.4. I was running Enterprise setup
of 4 node cluster. I got following error in postgres

Is somebody else is getting the same error?
Can you let know the reason for segfault in postmastermain and
suggestion/resolution for the same.

I would appreciate your help.

Thanks,
Anjali
