This is exactly what is happening to me. It appears to be right at 20 mins on both computers. I have never even tried multiclient. Nor, have I ever installed a clientless bot (or any other bot for that matter). There were no changes made but last Thursday it just started doing this. Given that I have tried different versions and combinations of agbot, nuconnector, loader/MediaPatcher I am beginning to wonder if there is something being sent from rev6 to terminate the agBot?? That seems to be the only common denominator so far... Hopefully, I am wrong though. :(
