Our web server is stuck at 100% CPU. Three days ago we were on CF9 and started running into this problem until the server crashed and wasn't salvageable. Luckily we had a fresh Windows 2008 Server R2 ready to go with a fresh copy of CF11 on it. I copied all the website files over and we were back up and running. A day later the CPU is back to 100% on the new CF11 Windows 2008R2 server. I also updated CF11 to the latest update 3 that was just released.
If I turn off the CF service the CPU usage goes back to normal. If I turn CF back on, the CPU goes back to 100% within like 5 seconds. So it doesn't seem like some slow running page or anything that eventually eats up all the memory or whatever. I'm not an expert at looking at the logs, but I don't see anything too out of the ordinary. The one thing that looks strange to me is I see this line over and over.
Dec 12, 2014 11:28:41 AM Information [ajp-bio-8014-exec-59] - Starting HTTP request {URL='http://zzen1wbudopwg.nchyt.com/encfm/en0024-ssj5iway6wvg/cbeim94a1s2kebu.php?do=194', method='get'}
That line makes me think we got hacked somehow, but it's hard to know.
I did up my JVM heap size and max size to 1024MB. We have 4GB of memory. And i changed teh JVM arguments to what's below based on a forum post. Nothing seems to help.
-server -XX:PermSize=192m -XX:MaxPermSize=192m -XX:+UseParallelGC -Xbatch -Dcoldfusion.home={application.home} -Dorg.eclipse.jetty.util.log.class=org.eclipse.jetty.util.log.JavaUtilLog -Duser.language=en -Dcoldfusion.rootDir={application.home} -Dcoldfusion.libPath={application.home}/lib -Dorg.apache.coyote.USE_CUSTOM_STATUS_MSG_IN_HEADER=true -Dcoldfusion.jsafe.defaultalgo=FIPS186Random
Any additional ideas on how to debug this or what to look at? Thanks!
