Apache went down on one of my nodes in the cluster. As it's a cluster, this wasn't catastrophic, as another node kept service. This happened while I was away from work, so by the time I arrived to fix things, the ISPConfig-Log has filled up with "httpd is down!" error messages, every single minute, for a few hours. The problem is fixed now. I'd like to clear away all these error messages, as they're no longer relevant. But the issue is that there's pages and pages of "httpd is down!!" to clear away and doing this one error message at a time is going to take ages. Is there some way to clear them all in one go?
