This message is coming from torque:

[15:15] 69-94-204-35:~/Desktop/torque-2.1.2 % grep -r "out of space
in buffer and cannot commit message" *
src/lib/Libifl/tcp_dis.c: DBPRT(("%s: error! out of space in
buffer and cannot commit message (bufsize=%d, buflen=%d, ct=%d)\n",

Are you able to use OSC mpiexec to launch over the same number of
nodes, perchance?
