Hey guys, I'm having a nasty production problem this morning.
All my pages with cfdocument tags on one of my servers are hanging on
PDF generation. I don't know if the code is single-threaded or not, but
I seem to have a gaggle of request all waiting on the first one.
The LONGEST request in the queue has a stack trace that looks like this:
"jrpp-9" waiting for monitor entry
- waiting on <179> a

EVERY OTHER queued request has a stack trace that looks like this:

What does the "waiting on <179>" mean in the first request? How can I
figure out what is going on?
I use SeeFusion, but I can't kill these threads. The run for up to 25
minutes and die with an http 500, no code at all.
Apparently I just found out cfdocument is single threaded on CF standard
(we have 7.0.2 on Linux).
Suggestions?
