>Description:
When mounted many smbfs like this:
# mount
//MNTUSER@PC1/WINSHARE1 on /home/pc1 (smbfs, noatime)
//MNTUSER@PC2/WINSHARE2 on /home/pc2 (smbfs, noatime)
//MNTUSER@PC3/WINSHARE3 on /home/pc3 (smbfs, noatime)
//MNTUSER@PC4/WINSHARE4 on /home/pc4 (smbfs, noatime)
(and so on)
And users and FreeBSD are actively using WINSHAREX (/home/pcX), then if some of these Windows PC's shuts down without unmount, the FreeBSD may reboot or going to the coredump. When mounted more than 10 smbfs, the reboots may repeated each day. Else reboots 1-2 times at week.
>How-To-Repeat:
Mount many smbfs (10 or better 20), simulate some reads and writes both on Windows and FreeBSD. Randomly turn on and off the Windows PC's wihout unmount smbfs.
