Getting "SW error "alarm in 4G ericsson site and cells are going down. When we restore site on old backup. Site work smoothly for some time, then again goes down.

Any log or alarm log you can share?

Hi, @Maxy. Does it rollback SW to previous version? Check lgg for crashes like following:

No: 25. Board restart. Reason: Kernel Crash. Program: kernel. Rank: Cold. PMD: pmd-kernel-0-20240104-112409. Extra: type_N/A

Can you share serial number of BB units?

Thanks Guyzz for the suggestion
