>Description:
I've encountered a strange problem while using FreeBSD 6.1-PRERELEASE for our file-server providing access via ftp and NFS.
The system crashes constantly with a kernel panic (panic: sbdrop).
Status netstat -m before crash:
337/473/810 mbufs in use (current/cache/total)
80/144/224/33792 mbuf clusters in use (current/cache/total/max)
244K/406K/650K bytes allocated to network (current/cache/total)
4009804/688682/688637 requests for mbufs denied
(mbufs/clusters/mbuf+clusters)
0/3/8704 sfbufs in use (current/peak/max)
0 requests for sfbufs denied
0 requests for sfbufs delayed
0 requests for I/O initiated by sendfile
131 calls to protocol drain routines
Also in the console appeared before panic messages:
"
in_cksum_skip: out of data by 13260
in_cksum_skip: out of data by 13260
"
and
"
gig0: discard oversize frame (ether type 23c2 flags 3 len 1518> max 1514)
gig0: discard oversize frame (ether type 23c2 flags 3 len 1518> max 1514)
sk0: watchdog timeout
"
The kernel is a GENERIC kernel with changes for SMP and semaphores support.

>How-To-Repeat:
It is necessary to try three times downloading a file with ftp nearby 1 GB for the speed 3-10 MB/c. System it is guaranteed receives panic.
P.S. I can give shell access to this server.
