Jim,
 
Thanks for the prompt (and informative) reply; we've eliminated the call from our monitoring and the servers seem much more stable.
 
It makes intuitive sense that this would be a difficult function to implement in a thread-safe fashion, but I have to agree that it would be better if this fact were called out in big bold type somewhere in the API documentation.  I've submitted a documentation bug in SourceForge (#745784); let me know if there is anything else I can/should do.
 
Eric

We have been trying to debug occasional (1-4 times/day) unexplained server
crashes under moderate load.  Our most recent testing points fairly strongly
to the command "[ns_server all]" which occurs in a trace filter we run for
system monitoring purposes.  We are currently testing an updated version of
the filter which omits this command, but I would still be interested to know
if anyone has encountered instability with the use of ns_server in their
environment.  The relevant snippet of code looks something like this:

 
 
 
Hi,
 
I don't believe "ns_server all" is thread safe and it would be expensive to make it so.  It's designed for occasional use in a debugging context, not as part of regular connection processing.  The docs should probably be updated to make this clear.
