My issue still persists and whenever Nesus Scans runs services go down of that node. Just now I tried to upgrade my galera to 4.12 and restarted the Scan, just hoping that it doesn’t go down.
I also tried to give maximum open_file_limit and also made max_connection = 1000, even that didn’t help
all hope is on the Galera version upgrade (referring to below jira link which mentions nesus scans crashes galera version 26.4.3 and fix is 26.4.12)
https://jira.mariadb.org/browse/MDEV-25068
But I think, for some Nessus impact the services and for other’s don’t because of the template used to Scan, in our scenario Nessus also runs some kind of Pen testing as per the CIS benchmark because of which at some point services goes down.
@Simon_Karberg What do you see in your general logs during scanning?
