Looks like I may have stumbled upon a pretty nasty CF9 bug. It affects my brand
new Red Hat 64 bit / apache setup in a reproducible manner, and I'd be interested
to know if it's a problem with my environment or a more general CF9 bug.
To replicate, place the following code in a template on a CF9 server. Then run
it a bunch of times. On my server after doing this, ColdFusion throws up
intermittent "Application server is busy" messages from then on, to all users.
The result is that the server is pretty much useless until reboot, running
normally for 10 pageviews, then timing out for 10, etc etc etc.
<cfcache timeout = "#DateAdd("d", "-1", Now() )#">
This is a test.
This "timeout" parameter was deprecated in CF7. It still worked in CF8, so I had
some lying around my code when I started investigating CF9.
Anyway, I'd be interested to know if this is a general problem or not. It could
probably present some very irritating denial of service type problems in hosted
environments if it's not just some weird fluke.
