When a node/agent goes offline, all of the jobs which are assigned to that agent are automatically cancelled by QuickBuild. It causes loosing the jobs which are scheduled for nightly builds. Sometimes agent is under heavy load and doesn't respond to the server for a short period of time. The QB thinks the agent is offline and cancels all of the jobs which are assigned to it. In fact, the agent is back to online in several minutes or so. I think the jobs are supposed to be waiting for the agent until it is back online and then resume the operations.
 This bug causes a serious issue for us here, since we can not afford loosing nightly builds.

 Thank you in advance,
