0% space on /var partition, a lots of files: storage[numbers].zip
Hi, I have a problem with storage on my partition /var. I got a info from my log that there isn't free space. After my investigation I found that there is a lot of file in directory /var/config/rest name storage[numbers].zip:
[root@:Active:In Sync] rest ls -alt | more
total 1926164
-rw-r--r--. 1 root root 1592770 2018-10-03 06:29 storage1538540986.zip
