thx @rohityadavcloud For the record: this has been impossible to reproduce in my test env (based on the instructions given by the relevant third party) - the problem is when doing multiple volume snapshots in multiple clusters, at the exact same time - ACS tries to add iptables rule inside SSVM to allow outgoing traffic (to vCenter I think) - and since there are multiple concurrent attempts to add iptable rule - some of those would fail (since iptable has an internal locking mechanism where it creates a lock while an rule is being added, so another rule/thread can not run) - so some of the snapshot jobs would fail as a consequence of not being able to add iptable rule. -- This is an automated message from the Apache Git Service.
