I have asked to my admin and he said that no log messages were present in /var/log, apart my login on the compute node. No killed processes, no full stack errors, the memory is ok, 1GB is used and 2GB are free. Actually I don't know what kind of problem coud be, does someone have ideas? Or at least a suspect?
