What kind of NFS mount is > being used (localhost mount?) Ok, I have some additional details, as I was able to mostly resolve the issue. Yes, mail is nfs exported, but that does not appear to be the issue in this case. pine is run from nfs mounted "/usr/local" pine would hang every time a user would go to send a composed message and wind up in "vmpfw". The "fix" was to go to the NFS server for /usr/local and do "mv pine pine.old; cp pine.old pine". This would (obviously) not affect any of the old pine's, it would however allow any new pines to run w/o problems. Note that any access to /usr/local/bin/pine.old on the client machine would result in a hang. Specifically "file /usr/local/bin/pine.old" resulted in "vmpfw" as did "cmp" and a couple of others. All of these worked just fine on the NFS server. The release in question is 3.3-STABLE from this past Friday (Nov. 12). -- David Cross | email: crossd@cs.rpi.edu Acting Lab Director | NYSLP: FREEBSD Systems Administrator/Research Programmer | Web: http://www.cs.rpi.edu/~crossd Rensselaer Polytechnic Institute, | Ph: 518.276.2860 Department of Computer Science | Fax: 518.276.4033 I speak only for myself. | WinNT:Linux::Linux:FreeBSD To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
