> When sasl server of client set a large expiration time, the timeout value might be overflowed, and cause the session timeout immediately.
>  
> [Here|https://github.com/apache/kafka/blob/trunk/clients/src/main/java/org/apache/kafka/common/security/authenticator/SaslServerAuthenticator.java#L694]'s the sasl server timeout's calculation
> [Here|https://github.com/apache/kafka/blob/trunk/clients/src/main/java/org/apache/kafka/common/security/authenticator/SaslClientAuthenticator.java#L692]'s the sasl client timeout's calculation
>  
> something like this:
> {code:java}
> sessionExpirationTimeNanos = authenticationEndNanos + 1000 * 1000 * sessionLifetimeMs; {code}
> So, if the configured or returned sessionLifetimeMs is a large number, after the calculation, the `sessionExpirationTimeNanos` will be a negative value, and cause the session timeout on each check.
