Timeout waiting for request semaphore

[ded]

Has anybody experienced the following error on a regular basis.

Timeout waiting for request semaphore
The server is unable to fulfill your request due to extremely high traffic. Please attempt your request again (if you are repeatedly unsuccessful you should notify the site administrator).

As far as we can tell there is no high traffic. We are running CF on a UNIX box connecting to Oracle.

Any ideas?

Cheers,
Duncan

Hey Duncan,

I've seen this happen on NT when there really wasn't a high load. If a cf script has a bug that causes it to hang and never clear out, it will continue to run and count as one of the "simultaneous requests". If the script is run enough, it will tie up CF with these hung requests so that CF can't process new requests because of all the old "hung" requests. New requests will eventually time out with an error similar to what you're reporting. You can see this on Nt with the performance monitor but I don't know what you can use on the Unix side to watch the CF request count. You might be able to tell with "ps" or "top".

Hope this helps,
GJ
