All Implemented Interfaces:

BPLAction

public class CleanUpAnyImmortalChannels
extends Object
implements BPLAction

This is a reasonably dangerous call. It appears that there is a bug somewhere in CAJ (or in the engine code that uses it) where we leave channels hanging around in an inconsistent state. Specifically, we seem to have an entry in the ChannelSearchManager but the channel itself has not proceeded to the tcp/ip circuit. This code forcibly closes these CAJ channels. Now; I'm unclear what that does to the engine layer above; it may leave the engine in a state where we need to restart it. However; I'm going to attempt this on one of the stuck PVs soon. I'd rather fix the bug in CAJ but until I can get Matej a reproducible usecase....
