Since we went to SR9.7, we've had a recurring problem, but one that we
have not been able to repeat on demand.  Occasionally, one types a Unix
command and either gets a "segmentation violation" or the Cshell
abruptly terminates.  Then the Cshell and all other Cshells active
hang.  New CSH's also hang, as do new BSH's.  The Aegis shell still
runs, and can be used to run at least some unix commands.  A "ps ax"
so derived indicates that the CSH's are in state "S".

Sometimes logging out and logging in helps.  Usually it is necessary to
shut the node.

It seems to me that the problem is mildly related to use of Vt100 and
TCP.  But I haven't hard evidence.

Has anyone else had this problem?  Is there a fix?
