Workflow Start condition Deactivation

[Raveendran, Simin (Infosys)]

Hi All,
     I have a scenario where the "Workflow Event Linakge Start condition"(SWB_COND)is getting deactivated of its own.
Is there any ways to prevent this. Please do let me know the tables or transaction for checking the activation logs.
Please note that I could activate this condition directly in production (Not promopting that system is locked for changes), 
Is there any cuztomization to lock the activation being done directly in production.

System   : R/3 Release 4.6C.

Regards,
Simin Raveendran.
