CTG6889W All of the available EXCI pipes are in use
This message is output when all the available pipes are in use.
The message is logged and the CICS® Transaction Gateway continues.
If the CICS Transaction Gateway attempts to allocate any more pipes, requests will start to fail with resource shortage errors. If you are not expecting all pipes to be in use at this point, consider increasing the total number of pipes available to the CICS Transaction Gateway. Alternatively, the CICS Transaction Gateway offers a choice of pipe caching models, which can reduce pipe usage in some circumstances. Refer to the product documentation for more details.
