We have 4 8.1.2 cluster running on an HP-UX 11.23 Itanium, repeatedly dying with the following log message: 2006-07-11 12:52:27 EDT [21582] LOG: received fast shutdown request 2006-07-11 12:52:27 EDT [21591] LOG: shutting down 2006-07-11 12:52:27 EDT [21591] LOG: database system is shut down 2006-07-11 12:52:27 EDT [21584] LOG: logger shutting down We can't figure out why it is shutting down. Nobody here is sending the signal. We don't have any cron jobs doing that sort of thing. We've also seen out of memory errors when this first started happening, though glance had not shown GBL_MEM_UTIL above 90% (with OS buffer cache max/min percents at 10%/3%). The box has 64gb of RAM, so that would seem to mean there was ~6GB of RAM available when it got the out of memory errors. Just in case, we shutdown several clusters, and restarted them, and now even with plentiful memory, they're dying with the same message. Any ideas? Ed
