ICX6610 10G Port Flapping Problems

[marin_raskovic]

Hi,
We are using two stacked ICX6610 switches and have several servers and storage connected to it. We have observed problems on our 10G ports - on server site (vmware esx hosts) we see constant link down/up events, and on storage ports we have CRC errors and port flapping condition.
No errors are found on 1Gb ports, no flapping, no CRC, no link state changes.
Sometimes we even get to APD event on vmware (we use 10G for NFS connection hosts<->storage).
FastIron version used is 08.0.10g.
Brief description (excluding 1G network connections):
3 ESX hosts named host1, host2, host3 are connected to 10G ports.
host1 - ports 1/3/3 and 2/3/3
host2 -  ports 1/3/4 and 2/3/4
host3 - ports 1/3/5 and 2/3/5
No teaming on hosts side - only virtual port based load balancing on virtual switches.
Backup server is connected to ports 1/3/6 and 2/3/6. Here we use NIC teaming at server side (static link aggregateion) and switch side - LAG.
Storage is connected to ports 1/3/1 & 2/3/1 and uses LAG.
From one stack member there is only one active uplink to rest of network - port 1/1/24.

I have copy-pasted our switch config below including port descriptions. Does anybody see some error in configuration?
