While loop error

I am writing some VHDL code that will take an integer and do some calculations and caonditional operations, and I keep getting this error:

Error (10536): VHDL Loop statement error : Loop must terminate within 10,000 iterations

Here is my code below...the error refers to the WHILE synchro_gear <= 16383 LOOP.

synchro_gear <= gear_calc*36;

IF synchro_gear < 16383 THEN

Synchro_36 <= synchro_gear;

ELSIF synchro_gear >=16383 THEN

i <= 0;

WHILE synchro_gear >= 16383 LOOP

i <= i + 1;

synchro_gear <= synchro_gear - 16383;

END LOOP;

WHILE i > 0 LOOP

full_range <= 0;

j <= 0;

FOR j IN 0 to 16383 LOOP

Synchro_36 <= full_range;

full_range <= j + 1;

END LOOP;

i <= i - 1;

END LOOP;

Synchro_36 <= synchro_gear;

END IF;

Please help me figure this one out. Thanks
