try reload
try remove and put back IOMs
call support
they will ask you do same steps again and send reports
then do RMA

(you can try other Timos too)
similar problem happend when in description was text " - " or similar. router didnt load whole config.

We also fight with this problem for several years. Card restart ('tools perform card power-cycle', or resit) cures the problem. Usually Alcatel agrees to replace it.
This problem can be vary painful, especially when tv mcast traffic flows through this card. But Alcatel cannot resolve this problem for us for five years.

Usually this means the on-board memory is experiencing an error. It can or cannot be service impacting depending on if the service uses that memory segment that's affected. The Three R process is the recommended method, reset, reseat, RMA. If I may ask, what is the device impacted? IOM? MDA?

It's the same procedure as PChip errors.

If it's the first time it's happened on that card and the errors aren't incrementing, monitor.
If the errors are ongoing, power cycle the card but bear in mind if it fails its power on self test, it may not come back so you might want to do this in a maintenance window possibly with a replacement card ready.
If that doesn't fix it, try re-seating then replacing the card.

You have the option of configuring "fail-on-error" if you would like the card to be shutdown automatically if these memory errors occur. This may or may not be appropriate depending on the redundancy in your network.
