I think I may be overreacting to a monitoring issue. The CPU utilization stays around 100% and the load jumps up for around 30min and then drops back down. Obviously this amount of time will vary, but as I roll this out to the rest of the environment, I want to minimize the alerts coming out.
I was looking for any possible settings which could ease clamd's CPU use. I've used ClamAV in other environments but I think monitoring was a little more lenient for high CPU load for periods less than 60min.
