[nos-bbs] Another Crash

JNOS has been running without issues for over a week. I have even issued two
other 'wpages kick' commands before this morning. As soon as I pressed
ENTER, the screen froze. The curser didn't even move to the next line and
the log shows that the WPAGES entries were processed. In previous crashes, I
could still log in via telnet and the other JNOS servers were still
functioning normally. Not today.
Here is what I have. If there is further information that I can provide, I
will be happy to do so.
JNOS ver 2.0j compiled using the latest code via RSYNC on 31 March 2012:
