I'm using Net::SSH::Perl to run a long series of commands on a remote system, basically using 'ls -laR' and 'cat' to locate and transfer several hundred thousand files to the local system based on a complicated set of rules. (Yes I know about SCP but it must be done this way, trust me)

The running time is expected to be several days, and this is fine with me.

The problem is that after exactly one hour and thousands of cmd() calls, everything just stops. No error messages, no nothing, the call just never returns. Any ideas what might be causing this and what to look for when troubleshooting?

When restarting, the script knows how to pick up where it left. Everything works for another hour, and you get the idea. The hosts are on the same gigabit switch and IP subnet, files are transferred all the time so idle timeout is out of the question.
