There is a defined connection limit in ScrewDrivers Print Server Agent v6 and Tricerat License Server v2. The setting defines a limit for active concurrent connections to the server. When the limit is reached, no new connections will be established with the server, resulting in failed license checks, failed printer queries, or failed print jobs. The default limit of 256 is in place to prevent the server from becoming unstable due to excessive resource usage.
If logging is turned on for the license server or print server, the following line will appear in the log file:
If the connection limit is reached during normal production operation, the limit can be safely increased. This is sometimes necessary in large environments.
