Description:
The Cosmic Environment run-time system for the hosts is made up of a
set of background processes that support a message passing interface
for UNIX processes. On some versions of UNIX, outputs to terminals
(such as error messages) can be blocked by a little used terminal
setting: stty tostop. If tostop is on, the outputing service process
will be blocked and subsequently killed by UNIX.
Symptoms:
1) Whenever something is to be printed by a processe in a
multicomputer process group, the process group is deallocated.
2) Whenever something is to be printed by a node process of a
non-multicomputer process group (non-cube), the node process is killed.
Temporary solution:
Disable tostop by "stty -tostop".
Permanent solution:
CE will be modified to disable tostop whenever CE is used.
