Thanks Hoff, yes this is a hobbyist system, but it is running a web server that is heavily hit, the web pages are sourced from an OSX server via NFS.
As I noted in a later reply, changing MPW_HILIMIT and MPW_WAITLIMIT has removed all the paging and just left me with 98-100% CPU activity every minute or so. At the same time, the system goes into 99% User mode activity.
So, my guess is that the RMS/NFS interface eventually gets swamped by the number of requests it has to process and convert. But hey, the *only* thing the system is doing is serving web pages via WASD, so if the CPU wants to spend nearly 100% of its time facilitating that, well.....there is nothing else for it to do! It has been running like this for 10 days without any other side effects....at least once I stopped the paging.
Thanks for the help!
