Yesterday for some reason the RFXCom Rx stopped receiving my sensors. After repositioning the Rx unit, some of the sensors came back online however the signal appeared very weak. I use HouseBot and with it comes an option to set Address Learn to Yes. I did that for all sensors and all but the wind meter came back online. Now this wind meter sits on my top roof and the battery state was still 100% so getting it down didn't seem like the first option. However after all my resources depleted, I got the wind meter down and changed the batteries after which it still didn't work. After a closer look, the battery clip was oxidated. After cleaning the clip, all went back to normal.
Once I had a garagedoor opener keychain and when the battery depleded, it started transmitting on 433MHz and thus jamming the complete 433MHz frequency. I guess the wind meter did the same thing. It appears that some devices just start transmitting when battery power drops below a certain level. Strange thing is that I still got 100% battery life so I didn't get triggered at first.
Hope this helps for some of you encountering the same issue.

Re: problems receiving
I had the same issue with MS13 (X10 RF) motion/daylight sensors. Once the batteries are empty (but not empty enough), they start jamming everything. Nice job to find out which one is causing this, when you've got a lot of those sensors... 
They're all gone now and replaced with my own sensors with supply voltage monitoring, email alerts etc.:
