Hello All, By the way, I found the source of the User Defined Signal 1. It was in my application. Just in case anyone is interested, I will explain how I debugged this:
First, using our in-circuit-debugger, I discovered which process was
running at the time the signal was raised, which was one of my
application processes. Then I wrote the following code snippet to
catch the signal in that process:
#include <signal.h>
...
void ouch(int sig);
void ouch(int sig) {
printf(OUCH! - I got signal %d\n", sig);
(void) signal(SIGUSR1, SIG_DFL);
}
...
int main() {
(void) signal(SIGUSR1, ouch);
...
}
NOTE: The above can be done for any unhandled signal type that is
killing the process.
Best Regards,
Jerry

There was some problems in session cleanup code in 1.12.4.
Could you try to upgrade to 1.12.6 and see if that helps to your
problems? 1.12.6 is suppoed to be rather stable and I think you should
be able to compile it on your cross-compilation environment without
any modifications...

Nope. I guess there is a heap corruption or similar problem cousing the
signal.
