If by that you mean "a kernel bug" then the answer is no. It's really a 
catch-all code for signals originating from inside the kernel. Looking at the 
sources, it looks like this may be sent in case there's a problem with the page 
tables (which would be a kernel bug or a hardware issue), but it's also used 
for things like "insufficient space to set up a signal handler frame" (which is 
definitely an application issue) and "IO on fd is possible (and application did 
not request a specific signal to be sent)" (which isn't an issue at all).
