You are the lead server administrator for a mid-sized e-commerce company. The web application is hosted on a farm of four Linux servers running Apache, fronted by a hardware load balancer. The load balancer currently uses a round-robin algorithm. Recently, the customer support team has received numerous complaints about slow page load times and occasional timeouts during checkout. You log into the server monitoring console and observe that one of the web servers, web03, has a CPU utilization consistently above 95%, while the other three servers are at around 30-40%. You connect via SSH to web03 and run the 'top' command, identifying a process named 'imagick' consuming 99% CPU. Further investigation reveals that this process is related to image resizing for product thumbnails, and it appears to have entered an infinite loop due to a malformed image file. Meanwhile, the load balancer continues to send requests to all servers equally, including the overloaded web03, causing some requests to time out. You need to restore performance immediately and prevent recurrence. Which of the following actions should you take?
