Stab in the dark: as Ian mentioned, you are probably overwriting your messages before they are fully sent / received, that's why sleep() helps.

I have a C application talking to a java server over zeromq / protobuf. The server is pretty mucht he same as in the examples ( https://github.com/imatix/zguide/blob/master/examples/Java/asyncsrv.java ) but the client is a C client.
I use windows 8 / MinGW. The communication runs well for a while but then crashes at the java server side, telling me the native code part failed: Assertion failed: check () (msg.cpp:207)
The messages I am sending are protocol buffers messages. Is this a known issue? I do not share sockets among threads.

No known issue - try cutting the client and server down as much as possible and posting them for us to take a look at. That check is a pretty simple message validity check, so if it's failing there it may be that there's some bad message reuse happening somewhere. Could be something weird with the win8/mingw building the lib.
