Try upgrading it to the verion 6.2.0.2
it could be a bug...
Also you should upgrade it just in case of this: If you read the release notes of 6.2.0.2
Symptom: An internal controller module stopped responding, corrupting data on the controller and
causing the controller to become unusable. The only resolution is to replace the controller. This
issue is resolved in ArubaOS 6.2.0.2.
Scenario: This issue was observed on M3 and 3000 Series controllers running ArubaOS 6.2.0.0
and 6.2.0.1."
6.2.0.2 fixes this... just in case you should upgrade it... as like it says it just have been observed on M3 and 3000 for now... but still...
When werd things happening without no explanation i always try to upgrade it and it solve the issue like 90% of the times in my case.
