We are not sure what happened but during the build, the log indicates that while executing a command, the ClearCase plugin did not get a response. We at this point couldn't kill the build through the hudson master. We tried killing the slave process and relaunching. The slave seems to be happy but the master is still trying to execute or waiting for the build on the slave to send a response? I cannot figure out how to fix this without possibly restarting hudson. I can do this if necessary but I would prefer to figure out how to either figure out what happened or at the very least kick hudson in the rear end and get it to forcefully kill the build. Looking at the hudson log on the master, nothing looks out of place.

On another thought, if I take a slave offline or disconnect it, shouldn't hudson auto-kill and clean up any builds that were active on the slave? At a disconnect the build would be junk anyway.
