I have a new centos 6 install. Randomly i get out of memory messages and my ssh file transfer dies. I have tried this in filezilla as well as winscp. I have disabled motd in ssh and i also had entropy problems so i enacted rngd -r /dev/urandom -o /dev/random but did not stop the out of memory errors. I am seeing the below in the logs. It only occurs during ssh file transfers.
