We've been having a terrible time with CF crashing since installing
4.51sp2. Here's what we've done:
1) Locked all session variables
2) Changed all CFX_http to CFHTTP
3) Changed all CFX_UUID to #createuuid()#
4) Reset CF to use "single threaded sessions"
We put out about 200,000 pages per day on our server. Before the upgrade to
4.51 (4.01) the system was fairly stable, but since then we've experienced
horrible crashes every 6 hours. Finally, we set "single threaded sessions"
and seem to be more stable (running about 150mg of memory climbing slowly)
If anyone has any Ideas, we'd love to hear them!!!
