Hmm, what's the possible cause?

well, my internet provider sent me that:

 

Possible causes:

 

 

Client applications are not closing connections, causing the number of connections to exceed resource limitations.

 

 

Broker is not running or there is a network connectivity problem.

 

 

Connection service is inactive or paused.

 

 

Too few threads available for the number of connections required.

 

 

Too few file descriptors for the number of connections required on the Solaris or Linux operating system.

 

 

TCP backlog limits the number of simultaneous new connection requests that can be established.

 

 

Operating system limits the number of concurrent connections.

 

 

Authentication or authorization of the user is failing.

 

Possible cause: Client applications are not closing connections, causing the number of connections to exceed resource limitations.
