Gilbert,
In the logs you sent, the assertion was thrown by pqexpire. Is this always the
case, or does it sometimes come from pqact or ldmd etc. Does the error generally
occur during the same time of day- or do you run any type of disk
defragmentation that might move part of the memory mapped data queue?

I'm throwing out things to check. Maybe Anne has more experience with Linux.
