I've been seeing the same sorts of problems on a P5-200. Single 4GB SCSI Ultrawide Adaptec 2940 UW 128MB RAM IPFIREWALL IPDIVERT NFS NETATALK Cyclades The system is an NFS client and web server. If NFS mounts are made *without* nfsv2 option, NFS services will hang after about 2 days. This machine has multiple network interfaces. ed, fxp, ep I too have come to the conclusion that it is long delays moving things in and out of swap. I'm happy to share more information if someone requests it. Note: the same setup was working fine running 2.2-STABLE. -Randy > I do not believe so.
