QuickBuild

When the server is under heavy load, it may disconnect the connection, causing the build status to become "canceled" #4649

quickbuild 15.0.8
Is it possible to add a timeout period instead of directly disconnecting and setting the status to "canceled"?

This does not seem like an overload issue. Please check your dns setting to make sure that the host is reachable:

java.net.UnknownHostException: xx.xxoo.com

The network is fine. There's another identical agent connected to the same switch, and that one has never gone offline. However, this agent experiences very high CPU usage during msbuild. I suspect there might be a network glitch, but the observed symptom here is DNS resolution failure. Can the agent be configured to retry and timeout on DNS resolution failures before disconnecting, allowing some tolerance time?
