Good morning. We are experiencing a severe problem with NFS freezing with
the following error message in the kern syslog:
Feb 11 05:59:47 alpha vmunix: svcktcp_reply: mbuf_send returned 32
Feb 11 05:59:47 alpha vmunix: rfs_dispatch: sendreply failed
Feb 11 05:59:47 alpha vmunix: svcktcp_reply: mbuf_send returned 32
Feb 11 05:59:47 alpha vmunix: rfs_dispatch: sendreply failed
I've checked the archives for this problem, and there is one entry about
this exact problem but no summary. There are other entries with
"svcktcp_reply" and "rfs_dispatch" but they appear to deal with things
besides NFS and are several years old, again with no summaries. I can find
no documentation on svcktcp_reply, mbuf_send, rfs_dispatch or sendreply in
the man pages.
The configuration of the machine is as follows (from the last reboot):
Feb 10 18:42:58 alpha vmunix: Digital UNIX V4.0A (Rev. 464); Sat Jan 24

Has anyone seen this? The NFS freeze-ups seem to be getting longer over
time, to the point that NFS is totally unusable. A reboot corrects the
situation for a short period of time (20 minutes or so), but over the
course of 4 hours or so NFS gets totally unusable. I *will* post a summary,
*if* I receive any replies.
Thanks in advance.
