What is the meaning of “caught signal number XX while (last) handling Perth.EV_APPLICATIONREADY”?
Old tricks for young players. Fatal error messages of this form generally indicate a major problem with your protocols. The number (typically 2, 10 or 11) refers to an operating system signal number intercepted by cnet (see /usr/include/signal.h). For example, signal number 2 will be caught and reported by cnet if you interrupt cnet from the shell level (signal 2 = SIGINT). The other common signals, 10 and 11, reveal significant flaws in the implementation of your protocols. Signal 10 (SIGBUS, a bus error) occurs when the CPU attempts to execute an instruction not on an instruction boundary (on many architectures, you’ve requested to execute an instruction whose address is not a multiple of 4). This error will generally occur when your programming corrupts your program’s stack and, in particular, you corrupt the return address of the currently executing function. When the current function attempts to return (to a now incorrect address) and then fetches an instruction whose address is i
