Hi,
I run a regular rsync job that runs from cron and copies stuff that gets created on a Windows smbfs share.
Starting about 10.1-RELEASE the VM has become unstable and started panicing.
I have narrowed the issue down to the aforementioned rsync job.
When I move the job to a different VM the the other VM starts crashing and the VM without the job becomes stable agin.
I have panics and crashinfos stored in /var/crash if anybody is interested:
root@noc2:/var/crash # uname -a

This is what I have in /var/crash/core.txt.0

Any tips on howto proceeed with this ?
I can setup a dedicated VM with a fresh install of whatever in case it helps.
