This is just heads up if you are running VSX with more than 4 SND / MQ cores and fairly high traffic volumes.
Please do not upgrade to R80.40 with jumbo less than 100 (fix is already included there) or request a portfix.
We upgraded from R80.30 take 219 to R80.40 take 94 and faced multiple issues:
- high CPU usage on all SND / MQ cores, spiking to 100% every half a minute
- packet loss on traffic passing through FW
- RX packet drops on most interfaces
- virtual router fwk was running constantly 100%
- clustering was reporting Sync interface down in fwk.elg
I don't want to go into the root cause details but lets say there is a miscalculation for resources required to handle info between SND and FWK workers. That's corrected in JHF 100 or above.
I just wanted to say that Checkpoint R&D was outstanding today, jumping on the case and working till it was resolved! Really impressed, I wish I could release names here but that would be inappropriate.
