Forget to stop at beakpoint at certain condition in php

[eric44]

Hi, using last sublime3 linux, tgz
xdebug is working good at 90% of use.
But, in my new code, editor not always stopping at breakpoint.
context, is important. With classic load php page, breakpoint is always working.
But using ajax, calling ajax on success, calling ajax on success (3 levels),
Breakpoints in third php ajax call are ignored.
If I put a breakpoint in javascript before last ajax call, breakpoints in third php ajax call are working again.
I suspected the speed of 3 calls of php files.
I tried same code with netbeans and another editor, they are stopped in all cases.
Regards
Eric
