We are running a program which SPAWNS commands frequently.  Most of the time,
these commands work properly, but every once in a while, the LIB$SPAWN will 
fail.  The return status for LIB$SPAWN is SS$_NOIOCHAN.  I realize that 
LIB$SPAWN needs to assign an I/O channel to create a mailbox but I can't figure
out why it can't find one.  I've checked for files which have been left open 
earlier in the program but no luck.  After I get this error, I open an existing
file successfully, am unable to create an output file, and from then on,
cannot even open any existing files.

Has anyone ever encountered any problems like this?  Any suggestions?  Thanks.
