This means a system call returned with an error code of -ERESTARTSYS when a signal wasn't pending; this is a kernel bug.
However, I've looked at the code to sys_wait4 (which implements waitpid), and I can't see where this might happen. Just before end_wait4, it does do something potentially dangerous in that it leaves retval set to -ERESTARTSYS, but in all of the code paths I can see, retval gets reset before it exits. The only thing I can think of is a compiler bug; what version of gcc are you using?
Puzzled,
