   Thanks for the information. We also experienced the same problems. In our case,
   the problem was compounded by a very large single ethernet (i.e. not really
   flaky but with a LOT of varied traffic on it). We experience the MALLOC problem,
   as well as a problem with the registry crashing intermittently. We are also running
   Apollo Beta regitries.

   Having finally gotten fed up with the whole mess, I but together a bandaid solution
   which appears to be maintaining the status quo. I have a script which is executed
   by CRON every hour. This script checks for a rgyd process. If it does not find a
   rgyd, it restarts the rgyd. If rgyd is running, it checks the size of the daemon.
   If the daemon execeeds 16M (i.e. double the size), the script stops the daemon
   and restarts it. A time/date stamp is placed in a file in `node_data/system_logs
   to record the event. Since doing this, our registries have been much better behaved.

   I recently did an audit of the logs. Since segmenting the network into 6 separate
   Apollo networks, the registries have hardly crashed at all. The new rgyds also 
   appear to be slowing down in their appetite for memory. However, I still need to
   do a more detailed study.

   If anyone is interested, I will post the script. It runs on BSD4.3 and is pretty
   simple. No support of course ;-).
