See thread with the subject > "rpc.svcgssd problem after updating client 1.2.2->1.2.3". I think the problem here is the same one we were experiencing, with large group memberships causing invalid writes to the procfs rpc channel files. If you strace rpc.svcgssd (or rpc.mountd, you should see it there too I think), you should see the write() calls being split into multiple 1024-byte sized writes, each of which get EINVAL (or -EINVAL, I forget) returned. I've submitted a patch for that last week, which is waiting on inclusion. If you want to verify, please look back in the archive and try the patch submitted in the mail with subject: [PATCH v2] nfs-utils: Increase the stdio file buffer size for procfs files It seems to work here, I'd appreciate if you could try it out and let me know if it works for you too :) BR Sean ÿô.nÇ·®+%˱é¥wÿº{.nÇ·¥{±þwìíèjg¬±¨¶Ýjÿ¾«þG«é¸¢·¦j:+v¨wèm¶ÿþø®w¥þ࣢·hâÿÙ
