Hello, I've noticed some previous postings about deadlocks in 6.4.2. At the risk of being irritating, I'd like to ask if anyone has seen this particular version of the problem: postmaster deadlocks leaving multiple ZOMBIE children with something like the following in the log file: NOTICE: Deadlock detected -- See the lock(l) manual page for a possible cause. ERROR: WaitOnLock: error on wakeup - Aborting this transaction NOTICE: Deadlock detected -- See the lock(l) manual page for a possible cause. ERROR: WaitOnLock: error on wakeup - Aborting this transaction ERROR: postmaster: StreamConnection: accept: Too many open files in system The suggested (and acceptable) solution seems to be to move to 6.5.x, but I'd hoped to get confirmation others had seen such - the 'too many open files' seemed new.
