Problem one NAV Instance & Shema Synchronization

itbozidar

NAV 2018 (Build 23019)
I have a problem with a NAV instance where every 1-2 days,
locks NAV service and asks to do Schema Synchronization with Validation, then it does everything normally.
We do not make any changes to the tables etc ....
that instance is used only by PDA-devices
Where I can see what initiate Shema?

Is the NAV servicetier the only application that initiates changes in the database?

I will see.
But - other instances working well, (we have 5 instances, and win and nup), only this one have problem, that is confused.

TallyHo

In that case first text compare the CustomSettings.config file of the instance with those of instances that do not have this problem. Is the instance on the same machine? Or a different one.

itbozidar

Yes, instances is on a same machine.
CustomSettings.config - are good. (all the same, only ports and names are different)

TallyHo

Did you check the Windows Application Log for any other exceptions on this servicetier?

itbozidar

Yess, nothing to see there.

Hmm.. compile the system (200000000..) tables with force.. as admin.
Use different NAV CU.
Now I'm officially out of options

Its very difficult to use another CU, to many working hours (min50H).
