If you use db backend, then most likely yes.

If you had to ask then you're not capable to solve it :)

As cruel as that might sound, unfortunately in my experience it's usually
true. You need a dba, or someone with dba capability, to fiind out WHY the
db backend is not responding. Search the list archive for common causes,
which can include:
- acct db too big
- non-optimum indices
- not enough resources (e.g. disk IOPS) in db server
- etc.

On freeradius side, there are things to make it "more friendly" with
database, like decoupled accounting. However I still recommend you find a
dba first before attempting to change anything on FR side.
