Debugging - Breakpoint View: breakpoint number increases while trying to launch debugger

Put breakpoints in your code and when you run the debugger, in the “Breakpoints” view the column ‘Number’ that indicates the breakpoint number increases while trying to launch  the debugger as if a millisecond counter was?
This behavior does not always happen, looks like as sometimes when trying to launch gdb fails, and tries ti launch the debugger multiple times (running multiple debuggers issue?)

Please see the screen-capture in attach.
