The payment retry queue began to drain. Her phone buzzed again: “Looks good now. What was it?”
Lena stared at it. Channel authentication mismatch. TLS renegotiation. That meant the error wasn’t internal in the sense of “IBM’s code broke.” It was internal in the sense that the queue manager had confused itself so badly that it couldn’t even log the real error properly.
STOP CHANNEL(PAYMENT.GATEWAY.01) MODE(FORCE) RESET CHANNEL(PAYMENT.GATEWAY.01) START CHANNEL(PAYMENT.GATEWAY.01) amq6125e an internal ibm mq error has occurred
Lena didn’t call IBM support. She’d be on hold for an hour. Instead, she killed the channel process manually—not the channel, but the underlying amqrmppa process on the queue manager side.
Lena typed back: “Internal error. Fixed with forceful disagreement.” The payment retry queue began to drain
Then a hard reset of the channel:
CHANNEL(PAYMENT.GATEWAY.01) STATUS(RUNNING) Channel authentication mismatch
She closed her laptop, walked to the break room, and poured cold coffee into a mug. Outside, the city was still dark. Somewhere in the IBM MQ source code, line 2,417 of amqzfchk.c still had a flaw. But tonight, it didn’t matter.
