Unfortunately since these are error messages within the mercd
driver, they don't mean a lot to me.  If you have access to the
source and can let us know what LiS function is being called and
fails when this message is printed out, that might help.  Although
it implies an allocb() failure, it's probably worth confirming.

Running out of buffers is not usual.  It may imply a memory
leak somewhere.  The fact that it happens after a while
tends to point to that.  I would suggest running the
"streams -l" command that you mentioned periodically while
the system is running to see if usage increases slowly
over time.  Running "streams -m" to display memory usage
in the failed case may also prove useful at determining
where the memory is used (where a leak exists if that
guess is true).
