UCRM Cashed



Our UCRM version is 2.14.1 and is installed on Ubuntu 18.04, yesterday morning UCRM crashed and when I checked on the OS console I saw this error "Overlayfs : missing 'lowerdir ".


So I restarted the OS & then the Docker and all system started working. I wanted to know the reason the UCRM cashed.


Here is the out of df -h


administrator@ucrm1:~$ df -h

Re: UCRM Cashed

Hi, you may try to update your docker.
