Hi
I assume that you have checked that there are enough diskspace on the Unix side?
Especially in tmp and in whatever partition the /etc/catngcampath is pointing to.
It could also be related to packet size transfer size on the network.
You can confirm this by doing the following on the Unix endpoint
camconfig fragment_size=1024
This should return with something like camconfig: New configuration record accepted.
If so, test it to see if you still have a problem.
If this solves it, run "camsave persistent" to save the new configuration.
If you still have problems, I think you are better off opening an issue
Cheers, Atle
