NFS nfs_getpages errors

[Eric Crist]

Hey folks,

We've got 4 servers running FreeBSD 8.1-RELEASE which PXE boot with NFS root.  On these machines, we run proftpd and apache 2.2.  Over the past couple weeks, we've seen a ton of errors as follows:

Sep 14 20:28:59 lion-3 proftpd[31761]: 0.0.0.0 (folsom-1-red.claimlynx.com[216.17.68.130]) - ProFTPD terminating (signal 11) 
Sep 14 20:28:59 lion-3 kernel: nfs_getpages: error 1046353552
Sep 14 20:28:59 lion-3 kernel: vm_fault: pager read error, pid 31761 (proftpd)
Sep 14 20:28:59 lion-3 kernel: Sep 14 20:28:59 lion-3 proftpd[31761]: 0.0.0.0 (folsom-1-red.claimlynx.com[216.17.68.130]) - ProFTPD terminating (signal 11) 
Sep 14 20:28:59 lion-3 kernel: nfs_getpages: error 1046353552
Sep 14 20:28:59 lion-3 kernel: vm_fault: pager read error, pid 31761 (proftpd)
Sep 14 20:28:59 lion-3 kernel: pid 31761 (proftpd), uid 0: exited on signal 11

These, in this case, occurred on three of the four machines until midnight after which all three of the machines had proftpd exit on signal 11.  The message above was for child processes.  At midnight, the logfile rotated, and newsyslog sent singal 1 to the parent process, which I think finally finished it off.  The fourth machine remained running and did not display these messages.

The number following 'nfs_getpages: error' changes for each cycle and I'm not certain if any of them repeat.
