ICX6610 10G Port Flapping Problems

Hi,
We are using 2xICX6610 in a stack for vmware esx hosts, storage and other servers.
1Gb ports are used for "normal" networking (client-server), and 10Gb ports are used for storage networking and vmware vmotion.
We are observing problems on network interfaces connected to 10G ports. At esx hosts we see port down/up situations (vmnic goes down and then up in same second), same on backup server (ms windows), and on storage ports we see link flapping situations. Also, we are faced sometimes with APD (all paths down) state for nfs datastores mounted from storage.
Jumbo frames are enabled at vmware side (vmkernel ports, vswitch), switch and on storage ports - 9000.
At vmware hosts side we do not use any kind of teaming - only virtual port based load balancing.
At storage side we use teaming, and ports on switch side are in LAG configuration.
Also, backup server 2 ports are in LAG, and teamed on server side.
No problems at 1Gb ports are found or logged, no vmnic down/up states.
To the rest of network only one port is used - 1/1/24.
FastIron version used is 08.0.10g.
Brief desciption
ESX host1 is connected to ports 1/3/3 and 2/3/3
ESX host2 is connected to ports 1/3/4 and 2/3/4
ESX host3 is connected to ports 1/3/5 and 2/3/5
backup server is connected to ports 1/3/6 and 2/3/6
storage  is connected to ports 1/3/1 and 1/3/2
VLANs 112 (storage network) and 113 (vmotion) suffers problems - only ports in this vlan-s have port down/up state changes.

Here is copy-paste of our running config from the switch. Can anyone see any mistake, problem, have a hint?
