@Araind Hi and welcome to the Forum 🙂 What release of SLES is this? `cat /etc/os-release` On SLES 15 SP1 I see in the last column `available` not cached, second to last is `buff/cache`. ---

@Araind Hi, I suggest opening a Support Request for this issue, mainly because it’s an old release, hopefully you have LTSS support? ---

I have opened support request and they have give only workaround not permanent fix. Like add cronjob entry to drop cache ,.
