Dear Mr. Ross,
Very thanks for your detailed reply! Now, i have more space for the MMPBSA, and it works well. Before I just allocated 2G for the MMMPBSA. But when I changed it to 3 G. Now, everything is ok!
Very thanks again!

It looks like your job was killed because the node ran out of virtual memory. The limit appears to be 2GB and your job needed more. This is strange though since a MMPBSA calculation shouldn't need that much, unless you are running nmode as part of it on a large system. How far did the calculation get before it died? Did it die on frame 1 or some point after processing a series of frames? The second case would point to some kind of memory leak which is entirely possible but might be tricky to track down. The first case would likely imply either an incorrect setting somewhere, maybe a crazy fine grid or similar setting / typo in a setting. Alternatively you may be trying to run this on a VERY large system.
It would help to have more details about your simulation in order to debug this further.
All the best
Ross
