Brisbane
So, I'm back in Brisbane and I've finally had a chance to post those remaining blog entries from ICA and CATaC. I've also uploaded my photos from the trip to Flickr, and I'll add them and some other materials to blog posts soon. Unfortunately, while I was away there were some problems with my Web and mailserver, so if anyone's emails to me bounced over the last couple of weeks, please resend them.
As I understand it now, the problem may have been caused by the Windows w3wp.exe service, which is part of the Internet Information Services (IIS) suite. This service handles Web server requests and can max out the CPU if too many requests come in at the same time (and at peak time, we sometimes get up to 1000 spam trackbacks per hour - none of which you see because they're usually all caught by the spam filter on the Website). I've now tweaked IIS by setting the 'worker process recycling' values to far lower limits - this means that the server will consume less system memory and CPU time before it starts to clean out old server processes. Hopefully this fixes the problem - and if anyone has useful suggestions for how to set the server limits, please let me know.
