It sounds like the system lockups are occuring perhaps due to disk I/O, with PostgreSQL being the program causing the
disk load past what the system handles.
How much load does this system normally have, when there aren't dumps/vacuums/reindexes going on? Trying to understand
how much load your system normally copes with before locking up.
?
As a thought, if this is really being caused by disk I/O loads, then it might be able to trigger it on demand with disk
benchmarking programs (just an idle thought). That could be useful to know about.
