Filesystem is approaching the maximum containers-En

Hi Floks

Please suggest our EMC DD containers are reaching maximum capacity. I can see below output from logs

Enviroment:OS 5.4.6.0-503967 Model: DD890

Constrain to upgrade code to 5.5/5.6 from customer side, required suggestions around this to avoid overflow and file system panic condition.
