If it helps anyone in the future, here's the information Rackspace gave us for tracking down the issue on a Red Hat Linux box: Well it took a bit of scouring on my part from what I can determine the cause of your high load and CPU usage appears to be from a non existent log file. First thing I did was run a strace on the PID and the process it forked: strace -f -p PID# -o trace.txt Then I inspected the trace file and found many instances where WebCatalog was trying to open and append permissions to non existent log files: open("/home/rtcanada/public_html/tvshows/ErrorLog.txt", open("/home/rtcanada/public_html/WebCatalog/ErrorLog.txt", I am not sure what permission or UID:GID these files should have but I created them with a simple 777 for now to allow your scripts to at least access them. After doing this your servers load shot down from over 37.3 to 0.12 and the CPU usage dropped from 300% for the WebCatalog process to 8.5%. ------------------------------------------------------------- This message is sent to you because you are subscribed to the mailing list .
