Beta not recognized on SG 135

I got this message:

Root partition is filling up - please check. Current usage: 87%

but I don't know if it has anything to do with it.

I´ve checked the Filesystem. The Folder /var/tmp/ is much big.

Thorsten,

are you already on 9.510-5 ?

of course!

of course!

Deleting AV-malware-name* -Files under /var/tmp solves the problem. THX 4 your help.

I guess I'm not gonna be the only one who had that problem. The 9.6 is more than 300 MB larger than the 9.5 last year.
