> When subscription is "enabled" in native client then the server endpoint name (host name + port)  is truncated if exceeds 99 characters resulting with failed connections towards servers (see logs in attachment). When subscription is "disabled" everything worked fine for what I tested. Also I performed some tests with java client and haven't found such limitation on endpoint name length.
> Endpoint name (e.g. server host name) + port is truncated within function addEP:
> {code:cpp}
> TcrEndpoint* ThinClientPoolDM::addEP(ServerLocation& serverLoc) {
>   std::string serverName = serverLoc.getServerName();
>   int port = serverLoc.getPort();
>   char endpointName[100];
>   std::snprintf(endpointName, 100, "%s:%d", serverName.c_str(), port);
>   return addEP(endpointName);
> }
> {code}
> Maximum length of FQDN according to RFC 2181:
> _The DNS itself places only one restriction on the particular labels_
>  _that can be used to identify resource records. That one restriction_
>  _relates to the length of the label and the full name. The length of_
>  _any one label is limited to between 1 and 63 octets. A full domain_
>  _name is limited to 255 octets (including the separators)._ 
> Due to above requirement the function addEP should not limit or truncate endpoint name.
