ERROR: SQLite query failed: UNIQUE constraint failed: config.var_name

delete from config a using config b where a=b and a.ctid < b.ctid;

it works well... also for all duplicate on db. 

I resolved.

create temp table saved as select * from config where var_name = 'DBConnectionPool.MaxLifetime' limit 1;

delete from config where var_name = 'DBConnectionPool.MaxLifetime';

insert into config select * from saved;

select * from config where var_name = 'DBConnectionPool.MaxLifetime';

how many lines this query will produce?

DBConnectionPool.MaxLifetime

 how many entries with such name are there? If two, delete one of them. 

What DB are you using, what is NetXMS version?
