Too much geocoding requests in less device

I have added 800 devices only but my everyday geocoding request is around 100k I am not able to find the issue.

I have already added:

• Filter of 200m per lat long
• Implemented cache

• What version?
• How many locations you have per day?
• What's your geocoding config?

• Version : is 5.12, modified for some features.

• Location: Don't have much idea but more than 700 vehicles are there and apporx 400 always running on same location

• Geocoding config:

    <entry key='geocoder.onRequest'>false</entry>
    <entry key='geocoder.ignorePositions'>false</entry>
    <entry key='geocoder.processInvalidPositions'>false</entry>
    <entry key='geocoder.format'>%f</entry>
    <entry key='geocoder.reuseDistance'>500</entry>

The second point is critical. You have to find out the numbers.

Today I calculate the uses so in 700 vehicle, it is using hundred 100K geocoding request everyday
