The /storage/log filesystem is low on disk space or inodes

Hello,

can anybody help with this errror message in my vCenter Appliance 6.0.0

I have one big file in this place. After reboot it is good for only one day.

deerlf7lvc1a:/storage/log # ls -l

total 1938852

drwx------  2 root root                    16384 May 13  2015 lost+found

drwxr-xr-x  2 root root                    4096 May 13  2015 remote
