What causes the warning 'rpc_zdelay_work_func => 0'
<p>When I run my application on either Android emulator or an actual device, the LogCat output is filled withing literally seconds with this message in yellow color</p>

<blockquote>
  <p>01-26 10:50:42.550: WARN/PrintK(24):
  rpc_zdelay_work_func => 0</p>
</blockquote>

<p>This started happening pretty recently and I don't even know what to look at, I mean this warning, supposedly it warns me about something, doesn't it?</p>

<p>A bit about the app features:
so the application uses a lot of communication over XMPP (uses pretty many threads for that), it has a map, uses the GPS, I draw some stuff on the screen myself from the code, I use some custom png graphics, the layouts of the screens are made with merge, Relational and Linear layouts. To me it seems quite a natural app, without any fancy stuff...</p>

<p>OK, this is really weird, today that warning is just gone! It disappeared like never existed. The only difference I can think of is that I unplugged the usb cable.</p>
