Hello, 
I am running BBB on two servers with identical specs (Xeon Quad Core 
with 4gb RAM, Ubuntu 10.04). They usually work well. However, from 
time to time, one particular server stops responding. If a client 
connects, it gets a "cannot connect to server" message. This used to 
happen every few days (the servers are in use for many hours a day) 
and BBB is cron'ed to --restart every hour. After a fresh install, it 
seems to have gotten better; alas, it still happens. The last time it 
happened, bbb-conf --check returned potential problems: 
# Unable to connect to port 1935 (RTMP) 
The following comes from red5 error.log. I don't know if it's useful 
at all:

This is an old bug ... we're updating to the latest version of red5 1.0-RC3 for 
0.81.  Closing this issue as we can open a new one if problems arise in the 
video.
