Possible Problem w/4.10-stable And SMBFS?

-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1

I am seeing a number of intermittent problems with SMBFS-mounted partitions
and am wondering if these are know FBSD problems or problems with the
Win32 servers:

1) After running for a very long time (weeks), SMBFS-connected directories
~   become very slow/sluggish for read/write.  A reboot of the FBSD machine
~   fixes this.  Error log shows:

~    Jan 18 16:36:28 yzx /kernel: smb_iod_recvall: drop resp with mid 15734
~    Jan 18 16:36:28 yzx /kernel: smb_iod_recvall: drop resp with mid 15736

~    This machine is running 4.11-PRERELEASE as of 12/14/2004


2) Again, after running for a long time (several weeks), attempts to
~   to long running I/O against an SBMFS-mounted partition, I get
~   a bus error and the following entries in /var/log/messages:

~    Jan 18 16:45:49 xyz /kernel: smb_iod_recvall: drop resp with mid 34907
~    Jan 18 16:46:06 xyz /kernel: smb_iod_recvall: drop resp with mid 39329
~    Jan 18 16:46:06 xyz /kernel: smb_iod_recvall: drop resp with mid 42496

~   This seems to be a problem primarily with very large files (100s of
~   megs to several gigs) - at least I've not seen this problem w/small
~   files.

~   This machine is running 4.10-STABLE as of 11/30/2004


Ideas would be appreciated...

Do you have any statistics about memory consumption/swapping?
top/vmstat/netstat -m
What is the cpu usage?
What is the number of open files in your system?

I'll focus on machine 'xyz' for now since its the one I care
most about:

Dell PowerEdge 1750 w/Dual 3Ghz Xeons and 3G of memory.

This thing idles most of the time as a mailserver for less than 150
users (both UW-Imap and SquirrelMail/Apache). CPU is typically less than
5% busy and top shows most of the memory inactive or free the majority
of the time. 'Sorry I do not have stats as of the time of the failure...


Don't have number of open files should be negligible (just *how* do you
get an exact count - I don't recall).

Output of netstat -m follows.  Thanks!
