Ok, I figured it out, not sure if this was stupidity on my part or just me expecting the system to behave a certain way. Basically I am using JMS with an indexing service and each client switched between two selectors, one looked like : (serverID="+serverID+" OR serverID IS NULL) and the other: (serverID="+serverID). My problem was both were open at the same time, so even though I wasn't receiving on the 2nd one, messages still got stuck. I do not know if this is correct behavior or not, but now I close and open each receiver when I am switching back and forth.
