GLPPXY050E Transaction request to back-end server server host name and port failed because too many connections are currently in use by transactions.

Explanation

Unable to send the transaction request to the back-end server because too many connections are currently in use by transactions. The proxy server will always reserve one back-end connection for non-transactional operations.

User response

Decrease the number of allowed concurrent transactions, or increase the number of connections to the back-end server and restart the proxy server.
