EOF on CC is not good kharma.
As MisterRogers said, it could be nearly anything; among the first is summing the SGA sizes of both databases and see whether that exceeds physical memory or even worse phymem+vmem; I've brought up (briefly) instances where my 'tuning' resulted in such enormous amoeba like things that "vi" had trouble coming up.
Because UNIX was being forced to swap and page. Bleah. (Thank goodness for development boxes..)
It does sound like a wierd and annoying IPC key problem, perhaps. Make sure you are (I know this sounds elementary, but....) setting your ORACLE_SID and ORACLE_HOME properly before attempting to start or stop an instance; I've seen that cause this, as well as worse.
