UCRM Cashed

Hi

 

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.
