Cisco ASA 5525 - higher cpu usage since update 9.12(3)12

[hash2k2]

On 13th of May we updated our Cisco ASA 5525 Cluster from 9.10(1)17 to 9.12(3)12.

Today I saw in our PRTG monitoring, that the cpu usage is know on 29-33 % during the night, when it was 3-5% before the update. The CPU usage raised exactly at the moment, when the update was done on 13th of May @ 7:30pm.

During the day we had usage of 30-45%, now it is between 35% - 65%.

Does anybody know something about this behaviour? Is there any kind of bug known?

According to the bug description, this could not be the reason. But thanks for the hint.
