Note 1087.0 NCL command fails from within DECmcc No replies

I am posting the following message for Karthik Murty (AKOCOA::MURTY).
Please respond to both him and me. Thanks,
Dave

I am trying to issue an ncl command from within mcc. Either from an
alarm fired procedure or by using the mcc spawn command. This commands
fails, though the same command works from the command line. When it fails,
I get a signal 26 (SIGVTALARM). What could be wrong? I have included the
cml trace file and confirmed that mop process was running on the system.
MCC> spawn
adm.wtn#ncl show mop client wtns1

| 6010.1 | Conflict with threads? | TOOK::MINTZ | Erik Mintz | Sat Jun 04 1994 12:52 | 4 |
My recollection is that DECthreads uses SIGVTALRM for scheduling. Is it possible that this conflicts with something in DECnet? | |||||
| 6010.2 | Yes. Known problem | TAEC::LAVILLAT | Mon Jun 06 1994 13:14 | 14 | |
Re .0 It is a known problem for all spawn commands within MCC. The first maintenance release of MCC on ULTRIX will have a fix for that, meanwhile try to avoid using executables that use also SIGVTALRM such as Ingres or cml, or ... use a small intermediate program that will do the right signal handling before running the actual command (I won't go into details here).
