This article explains the meaning of the "MQSS Error code: 0x2204cd" alarm that is seen on MX Series routers and indicates if any actions need to be taken.
The following log messages are seen on the Flexible PIC Concentrator (FPC):

1) Users may see a Major alarm reported when MQSS Error code: 0x2204cd is encountered for the first time.
2) A MQSS Error code: 0x22076e error is reported whenever there is a transient parity error detected in EACHIP memory Scheduler block hardware when it has been auto-corrected and no further action is required.
If the error occurs multiple times, take the FPC offline and bring it online again or restart the FPC during a maintenance window.
