We've seen CI systems consume all of our threads which causes the web UI to become non responsive. To address this increase the number of httpd threads from 100 to 150. Note that we do not modify sshd.threads beacuse sshd.threads determines the max number of git requests across both ssh and http. In theory what this means is that httpd has an additional 50 threads to process non git requests (for example web UI requests) which will hopefully keep that responsive even if git requests are max'd out. It is possible that we also need to increase the sshd.threads value to handle those git requests, but we will start by modifying one config value at a time. If we do bump sshd.threads we should increase httpd.maxThreads to give it that additional headroom. Finally, I believe this is likely to be safe as we doubled the size of our Gerrit server when we moved it to vexxhost. The old server was pretty well maxed out though so increase these values on the new server slowly and monitor the results.
