Unable to send message to queue number
An error occurred writing an internal message to a message queue. In UNIX and Linux systems, the Client daemon communicates internally using message queues. In systems other than AIX, the default configuration settings for these queues are too small to allow for large client data flows.
The Client daemon is unable to operate.
Change the configuration settings of the message queues to allow for large client data flows. The way that you do this depends on your operating system. For UNIX and Linux refer to the CICS® Transaction Gateway Information Center for details on configuring message queues. If this does not resolve the problem, contact your service organization.
