Thanks for the response Tom. The checkpoint process seems to be just sitting. I'll post the details of strace/gdb in the morning.

(strace'ing it would reveal this) If it seems to be just sitting, could you attach to it with gdb and get a stack trace to find out where it's sitting? The only known cause of checkpoints not proceeding in 7.4.* is that long btree CREATE INDEX operations can block them. But 24 hours sounds pretty long for a CREATE INDEX too ... regards, tom lane --------------------------------------------------------------------- This transmission (including any attachments) may contain confidential information, privileged material (including material protected by the solicitor-client or other applicable privileges), or constitute non-public information.
