So I just checked my servers rpt file because it was over 500mb in about 2 days. It gets to what I assume is the end of the ALiVE portion like this

20:41:36 ALiVE [m_6|45] Module ALiVE_SYS_LOGISTICS INIT COMPLETE TIME:  1.59766
20:41:36 "perfMonitor.fsm message sent: [["Type","Data"],["FPS",3762],["FPSMIN",847],["CPS",6],["PLAYERS",1],["LOCAI",70],["REMAI",0]]"
20:41:36 Error in expression <(count _customCode > 0) && (diag_tickTime >= _c>
20:41:36   Error position: <_customCode > 0) && (diag_tickTime >= _c>

and then I have over 7 millions lines of

20:41:36 Error in expression <(count _customCode > 0) && (diag_tickTime >= _c>
20:41:36   Error position: <_customCode > 0) && (diag_tickTime >= _c>

repeating over and over and over and... well you get the idea.

Does this look like something from ALiVE?

My mod line looks like this

-mod=@CBA_A3;@TFAR;@cTab;@ALiVE;@ace;@VCOM_Driving;@P_ASR_AI;@Spyder;@CAF_AG15;@CAF_AG_Audiopatch;@3cb_baf_vehicles;@3cb_baf_equipment;@3cb_baf_weapons;@3cb_baf_units;@Foxhound;@Husky;@CUP_Terrains_12;@aliveserver; -world=empty 

Anyone have any ideas where I should start looking for the culprit?

Excellent, that appears to be the issue, I deleted and replaced the module and noticed I must have somehow inadvertently deleted the perf monitors.

Thanks heaps

@HeroesandvillainsOS  it was completely my fault, you know those times when you go to delete something or type and you're in the wrong field and you edit stuff without realising it? Yeah I had deleted all the entries in the Custom Perf Monitors field except for "[["
