In PBA mode connections fail and new port blocks are not allocated when subscriber attempts more than 512 connections to the same server IP and port.
Subscribers can initiate only 512 connections to particular server IP:port.
PBA mode is configured on the LSN pool and inbound connections setting is set to disabled.
Set 'Inbound connections' setting in the LSN pool to 'Automatic'.
