CENTOS 6.7 x86_64 xenpv – WHM 54.0 (build 1) 4GB RAM 4 CPU
Recently I've started to encounter a problem where sites are going offline temporarily during the nightly backup to S3. This is now being accompanied by the chkservd process becoming non-responsive. The backups used to take approx 40 mins but now take 6.5 hours to complete and sites are offline for up to an hour.
I run 12 not very busy sites on this server with backup sizes ranging from 10MB to 4GB. Going back several months, there was one site with a large db (2.5GB) that would go offline for a minute or two during the backup. I put this down to the db size and because no other sites were affected I thought it was safe to ignore. Now however the problem has grown to impact the entire backup process.
My limited troubleshooting skills show that during the backup process memory might be being exhausted:
total: 3904496
used: 3886328
free: 18168

I could add more memory but don't want to waste the money if it won't solve the issue. How can I properly troubleshoot this?
I'm happy to provide more info but not sure what might be useful.
Many thanks
