We use/used: reiserfs - rw,noatime,nodiratime,notail,data=journal ext3 - noatime,nodiratime,data=journal If you weren't using "notail" on reiserfs, that would definitely have a performance impact. > Okay, I think that we had a different kernel memory bug. > > We were running out of memory after 24 hours, and a 20 line test program > could exhaust memory in seconds.

Do you know where the memory leak was occuring? We never encountered anything that would exhaust memory like that. We did encounter a bug which caused a deadlock inversion problem and would causes processes to get stuck in D state. It appears the code path that causes this has been totally removed sometime between 2.6.20 and 2.6.22, so I think we can finally drop that 1 line patch we've had to apply for the last couple of years...
