Hello, I've been seeing something weird on a site we built, an interchange process is running for a long time and eating up processor and memory, here is a capture from top: PID USER PRI NI SIZE RSS SHARE STAT %CPU %MEM TIME CPU COMMAND 30930 ic50 15 0 36476 35M 2232 R 98.1 2.3 103:59 0 interchange As you can see it's taking a lot of CPU time and eating up a lot of the available CPU. If we let it run long enough the site will no longer respond and an Internal error is presented in a web browser. Is there a way to see what IC is doing? Perhaps some debugging statements in key places will let us know what IC is doing and why it's taking so much CPU? This state happens even after a restart and is pretty sporadic how long after a restart it occurs.
Check for bots. I have seen this when rude bots (10-15 hits/sec) hit a slower system.
Which led me to ban the bots from alexa.com. (which did not follow my robots.txt)
