   Ext2fs doesn't get a lot of testing and has been known in the past to be
a little buggy. I wouldn't be surprised if the 3rd panic was indirectly
caused by things that happend in the first. The second panic sounds like
a kernel misconfiguration - for busy WWW servers, you need to be careful
about how you many network buffers you configure. This has been talked
about to death in our lists, but nonetheless, you can probably fix the
problem with something like

options "NMBCLUSTERS=10000"

   ...in your kernel config file. If the system runs out it will eventually
panic. The only solution is to configure enough buffers to handle the peak
usage.
