Error message in /var/log/messages after upgrade to R81.20

[Mikael_Trosell]

I upgraded a TE1000X box from R81.10 to R81.20 It seems to work fine except for one problem.

In /var/log/messages there is a large amount of log messages of this type.

I had problems with the disk space on /var/ log when the message file was 120 Gbytes...

Has anyone encountered a similar problem? I haven't found anything similar when I searched around

Hi - have you opened a ticket with TAC? 

I found 2 similar issues and it seems the message are harmless. I suggest opening a ticket so that your case is also investigated. You can point them to this post if needed so that they can refer to the other cases.

Hi,  I'll open a case and see what the result is. I have to increase "log rotation" so that the disk does not get filled in the meantime.
