I ran into the same problem, the slave was unable to recover from the state, don’t know what triggered the problem. There is plenty of RAM still available on the system though, I am using 3.1.1 Version on RH Linux 3.2. In my case it is very frequent, purposefully I didn’t run ‘nsdc patch’ for couple of days. I did nsdc patch, rebuild and reload. Nothing seems to fix the problem, I had to restart ‘nsd’ to fix.
