Unfortunately it could be, or it may not be. :( 
lowcomms_get_buffer() can return NULL if either a) there is no memory to
allocate a page, or b) the DLM has been shut down. If that happens, -ENOBUFS is
the result. On balance I would suspect that b) is more likely in this situation.

One oddity in that log is that the DLM took 10 minutes to shutdown after CMAN
decided it had to leave the cluster - or did those 34980 lines have to go down a
serial console?
