i have tried with almost no users on. i see the same issue.

I had narrowed it down to needing a newer/larger appliance that was rated for higher throughput. I don't like the throw more money at it approach so I thought I would throw the question out to see if I was missing some configuration that would clear up the issue.

CPU doesn't look like it ever gets to 100% but it does get high (looks like >85%) during large transfers. the system shows about 450 clients.

I do not see any TCP Zero or Window full messages. I do see a lot of "Ignored Unknown Record" messages in Wireshark. I am seeing some packet loss but not on the same frequency as the transfer drop. I do have traffic shaping configured but in this case the source has been whitelisted so it can use the full bandwidth.

I have an MX100. I have been seeing this issue since I increased our bandwidth to 500 Mb/s the speed drops out about every 25 seconds when transferring large files. I usually notice this during cloud backups, but have seen it with other large file transfers also. I am looking for suggestions to try and resolve the issue since it drastically increases the time needed for the transfer and can cause the transfer to fail going to FTP sites.
