Hi, All,
Here is the pstack information from dbx.

As said - you're calling:
pthread_mutex_lock(NULL);
that's clear from the stacktrace. It's called from cmgCall::sendEventIn(),
but then I've already told you that ...
You can't pass an invalid pointer into pthread_mutex_enter().
Hence the question: Are you willing to share information about this, i.e.
give us the sourcecode for that class ?
Are you planning an opensolaris project around this, since you're asking
for debugging assistance on an opensolaris forum ?
