Neil,
We have "patched" CFMX with Updater 2.
Everything I have read about Queued Requests/Excessively High Threads and
how jrun spawns many more threads talks about changing up the max requests
in the server-inf/jrun.xml file -- here are our setting there:
<service class="jrun.servlet.jrpp.JRunProxyService" name="ProxyService">
<attribute name="port">51010</attribute>
<attribute name="deactivated">false</attribute>
<attribute name="activeHandlerThreads">20</attribute>
<attribute name="minHandlerThreads">10</attribute>
<attribute name="maxHandlerThreads">500</attribute>
<attribute name="mapCheck">0</attribute>
<attribute name="threadWaitTimeout">300</attribute>
<!-- set this to false for multi-hosted sites -->
<attribute name="cacheRealPath">false</attribute>
</service>
The machine seems to be running fine with 20 (ActiveHandlerThreads) and I am
thinking I will run some test on our QA machine with it turned up to 30 or
40 and see what happens.
Jeremy

Neil,
We actually spent almost a full month pouring through all our code on a QA
cycle making tweaks and working to make it more compliant with CFMX
(Hardware wise was the same config as our Production minus requests going
through the firewall). We even re-wrote really old code that wasn't as
efficient as it should be. Plus we to the extent of creating LoadTest
Scripts and didn't have any challenges -- as we all know though it is almost
impossible to simulate a full production environment with users hitting the
site.

There are so many of these issues, when you upgraded did you run an
extensive test on a pre-production machine or was it "lets upgrade! it will
work fine!!"

Subject: HELP -- CFMX Very High Queued Requests/Hanging
Everyone,
Our server is supporting a couple of sites with the main one getting about
10,000 unique visitors/day -- decent about of traffic. We switched from CF5
to CFMX about 1 week ago and every now and then the server seems to just
hang with no idea why other than LOTS of queued request (25-200). Sometimes
it will recover and process all in the queue after about 1 minute and then
other times it just hangs. The CPU isn't high nor is the RAM. It can hang
up to 2/3 times/day and sometimes not at all.
Server Config? We are running Apache 2.044, CFMX Enterprise (updater 2),
JRE 1.4.03 on Dual P3 with 1 Gig of Ram with the database (SQL 2000) on a
separate server.
No we do NOT having any "locking problems" with server, session or
application variables because all of our apps use client and request
variables.
Their has been a couple of very long threads on CFForums about this to
seemingly no avail -- other than to point out that it could be CFMX JDBC SQL
Driver having thread problems.
Anyone tried using a different SQL JDBC driver? If so which one and did it
help?
Anyone out there figure out a fix other than adding more servers and
creating a cluster? And we would prefer to NOT go back to CF5 unless we
have to.
Thanks,
Jeremy
