It would also be interesting to see the output of these commands when the event is upon you:

"lsof -p <pid> | wc -l"  #where pid is the process ID of smbd.

or

"ls -la /proc/<pid>/fd | wc -l"

if this is linux and lsof is unavailable.

Check this number against "ulimit -a <user smbd runs as>"  and make sure you are not running out of file descriptors.

also if possible check output of:

"vmstat 1"

Pay attention to the si/so io and wa columns and see if you are thrashing on the swap, general disk access, or suffering
from huge io wait times. (which could be caused by any of the others being high values)

lastly, check dmesg and see if threads are being killed off by something hitting another limit.
