I am observing similar problems with high load (not necessarily high 
number of connections) with 5.4-PRERELEASE from March 22 on a Tyan K8SR 
motherboard dual Opteron system running PostgreSQL 8.

I am not ready to rule out hardware problem, though, as I have had a 
fair number of ethernet port timout+reset reported by the kernel.  I 
shall try disabling SMP to see what happens.  It is times like these I 
wish there was an equivalent to the Dell diagnostics suite for other 
machines :-(  If only Dell would sell Opteron!
