I noticed the error: Problem with ptr packet: OVERFLOW
when running X release 1.2 this afternoon - what does this mean?

This generally indicates that the system is running out of
the streams resources NSTREAM, NQUEUE, or NBLKxxx. Try running
"netstat -m" to observe system usage statistics, and increase
these tunables accordingly.

The crash command provides a much better mechanism for viewing the
streams statistics.  Just log in as root, run crash (with no
arguments) and then enter "strstat" which will get you something like the
following:

(which shows that I am majorly overallocated for just about all of these).

I should have tested netstat -m before I posted my response.  Contrary to 
the manual the netstat -m does not show the network private buffer statistics,
it shows the streams statistics. The output of strstat in crash is almost
exactly the same as the output from netstat -m (although netstat -m is
*much* faster and may be run by mere mortals).

Sorry for the confusion.
