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. -DG David Greenman Co-founder/Principal Architect, The FreeBSD Project To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
