Tony,

Did you ever get a resolution to this issue?  A customer here is seeing 
similar behavior.  He hasn't exactly pinned it down to the wwwproxy, but 
every few days, the console logs "swap space below 10% free" and shortly 
thereafter the system gets so slow he has to reboot.

Sometimes he has to cycle the power to get the machine to come back up 
cleanly.  He does exit out of the GUI and logs out of root whenever he 
isn't actually at the console.

I've installed similar systems on the same platform and never seen this 
before.  This system is very heavily used during the day, however.

System is AFWU 2.1 on DUNIX 4.0a on an AlphaStation 255 with 96 meg of 
memory and a single swap partition.

How can I tell which processes are using swap?  What else should I 
monitor when this shows up?  I've thought about running a cron job 
which does things like 'ps aux', 'swapon -s', etc. every half hour or 
so.

I believe this was resolved by putting the AFWU V2.1 wwwproxy on the
system, and at the same time increasing the amount of swapspace by a
large amount.  The problem is probably caused by WWW cache management
working in a "non-optimal" way.  If this is the case, turn off the
cache as a short-term workaround.
