Thanks Alan, What value should I change max value to? I increased it from 40 to 200, is that enough? The following logs were received during the burst and for a certain period afterward: Jan 15 03:54:15 srv-1 radiusd[581372]: rlm_sql (sql): Cannot open new connection, already at max Jan 15 03:54:35 srv-1 radiusd[581372]: rlm_sql (sql): No connections available and at max connection limit Jan 15 03:54:38 srv-1 radiusd[581372]: rlm_sql (sql): No connections available and at max connection limit Jan 15 03:54:40 srv-1 radiusd[581372]: rlm_sql (sql): No connections available and at max connection limit On 1/15/26 15:13, Alan DeKok via Freeradius-Users wrote:

In FR 3.0, in the NAS network link interruptions, I receive the error *"rlm_sql (sql): Cannot open new connection, already at max"*.
What should I pay attention to when increasing the *max_requests* value? Increasing "max_requests" won't fix an SQL connection issue. You should instead look at the "sql" module configuration. There's a "max" connections setting there.
