Hey @bharat_gole 

9.0 flat was pulled from the portal due to some major issues. Please upgrade to 9010d if you need 9.x, otherwise we would recommend 8095g. As for your actual issue, it looks like the egress queue 0 is being overrun. This could be due to many issues (bursty traffic, etc.). Realistically, I would recommend opening a case, so we can take a closer look (see my signature). You may be able to resolve this by playing with the egress buffers, but it is hard to say just off that output. See here for more information:

HI Benbeck,

Thanks for reply.

we already open this case. team is looking for that but no luck till now.

we want to 9.x Firmware because of IP DHCP binding scalability has been enhanced to support up to 3000 clients & 8.x not supported.

if you want the case number then i will share with you. Please let us know.
