Kernel Bug



	I have a DB server running ext3 under fairly extreme load. The
system is a Dell 2550 (Dual P-III 1Ghz with a gig of RAM) running RedHat 7.2
with the stock 2.4.7-10 kernel. Things have been swell for 95 days, but I
just got bit:

Linux  2.4.7-10smp #1 SMP Thu Sep 6 17:09:31 EDT 2001 i686 unknown

	Is this a known bug? I'm not finding anything in the errata. I have
a different machine running a stock 2.4.18 kernel, and I known about the
RedHat bugs in 2.4.18-3. Does the stock 2.4.19 kernel represent the most
uptodate and stable version of ext3?

Many thanks,
