The dmesg shows that swap has not been touched free and total are the same, so this system is not running out of total memory per say. I keep thinking it's something to do with lowmem vs highmem 32bit vs 64 bit, but again no changes and I'm getting hit nightly on 2 different servers (running slon, so switched over and same thing, even disabled memory over commit and still got nailed. Is there anyone familiar with this or could take a look at the dmesg output (off list) and decipher it for me? this is a Fedora 12 system, 2.6.32.23-170. I've been reading and appears this is yet another fedora bug, but so far I have not found any concrete evidence on how to fix it. Fedora 12 32gig memory, 8 proc postgres 8.4.4, slony 1.20 5 gigs of swap (never hit it!) Thanks Tory
