I just got my MFC reminder for this change and I don't want to request permission for the MFC until I know for sure that it (or 1.636, which is also has a pending MFC) isn't the cause of the problem. What else is happening on machine when the symptoms occur? I would only expect vfs_subr.c 1.636 and 1.642 to affect the behaviour if there was a lot of file system activity that put pressure on the system to free up vnodes.Received on Mon Aug 29 2005 - 16:15:48 UTC
