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. >Fix: >Release-Note: >Audit-Trail: >Unformatted:
