Token services found an invalid token: token=value , number of blocks=number , retry count=number
An LUW token references a block that is not allocated. It refers to an entry in the token map that cannot be located.
The current ECI request will fail. If the failure occurs while continuing, committing, or rolling back an extended LUW transaction, the request will fail with ECI_ERR_LUW_TOKEN. The CICS® TG will continue to process requests.
Ensure that the application is not sharing LUW tokens between threads, or attempting to use an LUW token associated with a completed transaction. If this is not the case, and the target CICS region shows mirror tasks waiting on resource type RRMSEXIT, contact IBM support. Restarting the Gateway daemon should allow any such mirror transactions to end.
