The windows user "service.sql" is only used as a service user of the NAV ( 2017) , and c folder of the server is totally filled because of the produced temp files ( each has size 70 mb, so far total: 213gb ) in temp folder of this account. Please see the attachment . Do you know any reason why NAV produces this temp files, any recommendation to stop NAV from creating this files? We do not use this windows profile for any other purpose, that's why we just suspected NAV.
Oldest file created on 2022-05-26 , so this is not an old behavior of our NAV setup.
