Hi,
TCP maintains a backlog of waiting connections if a server application
doesn't accept or deny connections.
PostgreSQL has a setting max_connections, so it won't accept any more.
So there are two solutions:
* Lower the number of concurrent clients
* Increase the max_connections setting in postgresql.conf
Regards,
Holger

Hi,
The max_connections are 5000.
but I am getting the alert on mere 500 connections.
Please suggest why is this happening.
Regards,
Atul

Hmm ... the other responses presumed that what you are running into
is ERRCODE_TOO_MANY_CONNECTIONS (53300), but I'm not entirely
convinced, because the standard wording of the message for that
is "sorry, too many clients already". I think you have some
client-side issue. Alternatively, maybe you are already using
a connection pooler and this message is coming from that.
In that case, you need to reconfigure the pooler to allow
more clients.
regards, tom lane
