What distro / kernel version of linux are you running? We have a
similar issue with late model hardware and RHEL4 recently here at
work, where our workstations are running out of memory. They aren't
running postgresql, they're java dev workstations and it appears to be
a RHEL4 on 64 bit problem, so that's why I ask.
When Java sees that your machine has got plenty of RAM and more than
one CPU, it assumes that it's a server and you want to run just a
single VM, and configures itself to use a fair chunk of available RAM.
This is more or less a Sun-specific issue. Other Java implementations
make different choices.
Yeah, but these boxes run out of free mem, buffer, cache and swap. On a
machine with 4 gigs ram and 2 gigs swap, something is seriously wrong
when all that ram just disappears, and it isn't just with java apps,
though most of what the developers run are java apps / servers. We've
had a machine with mozilla (no java extension in it) run out of memory
just sitting idle.
