this output increase for me when , I do httpd -k restart every 3 min interval,
every restart it increase gradually. are you doing restart and includes other
shared modules without third-party modules?
do you mean without these 4 modules auth_ax_module (shared) ,auth_jwt_module
(shared), axapi_1_module (shared), web_apis_module (shared) you tried?
If so I will try without these four module.

how to include this while doing gdb?
I usually do "gdb -p pid"
