I'm having an issue with a block of machines running debian 6 (ARM). When I ssh to them I'm only able to get about 3 lines of output from any command (eg 'ps -ax') before the session is locked up and must be killed.
Running 'ssh -vvv' doesn't show any errors.
EDIT: I can get single commands to execute:
ssh root@server "ps -ax". If I login and try the same command the lock-up occurs.
What else should I try to see what's going on?
