Aborted connection

[Aurélio de Souza Ribeiro Neto]

   Hello,

       I´m using FreeRadius 3.0.19 and MySQL 5.7, and I got many errors in
   mysql log like:

       Aborted connection 17531 to db: 'freeradius' user: 'FREERADIUS'
   host: 'XXXXXXXXXX' (Got an error reading communication packets)

       My database is up to date and querys running very fast, something
   like 0.003s

       When it happens I have this messages in freeradius LOGs:

       WARNING: (131915) WARNING: Module rlm_sql became unblocked
       Error: Received conflicting packet from client ce-popfd-rb port
   49756 - ID: 101 due to unfinished request in module sql.  Giving up on
   old request

       What I need to adjust do solve this issue?

       Thanks
