Hi Tom, You appear to have been correct. :-) The being led to believe it was connected to huge_pages turns out to have been a coincidence since we had been working with huge_pages. Postgres happened to crash close enough to trying the huge_pages and did not appear to crash when they were disabled led us to make that conclusion. After a bit more careful testing we found out that postgres did indeed crash even without huge_pages. The setting in the link appears to have resolved this issue.
