I've been experiencing this issue for a couple of months now where my ESX hosts lose connectivity with my iSCSI SAN vmfs volumes.
As a results the ESX hosts enter a nonresponsive mode the associated VMs disconnect and the only remedy is to reboot the host.
This issue happens randomly . I have escalated this issue with VMWare but I haven't had any solution to the issue yet.
I see no errors on my switches and there are no hardware issues as well. My SAN infrastucture is solid and there are 2 paths for every vmfs volume.
Did anybody else experienced a similar issue?
have you checked within the following directory when your error happens?
it could highlight some problems...

Thank you for your responses. Here are some more details:
The iSCSI SAN software is Datacore Sanmelody 220.127.116.11 running on 2 HP Proliant G5 servers.
The storage attached to each of the servers is an HP MSA70 and all the iSCSI SAN Volumes that are presented to my 4 ESX hosts are mirrored.
I have two iSCSI swithces HP Procurve 1800G-24 that are trunked together.
My SANLELODY servers are using NC360T NICs. I team two NICs and have one cable connecting to each iSCSi switch.
Each ESX server uses two NICs as well for the iSCSI Network.
Please let me know if you need more information.

What model of NICs are you using for the iSCSI connections on your ESX hosts? Are they iSCSI HBAs or regular NICs? If you're using the software iSCSI initiator, how are your two iSCSI NICs configured on the ESX hosts?
In what way this could be a spam? On what planet?
I'm just trying to help Themist. In the way I can.
On the planet where nearly every post you've made is a "helpful recommendation" that the poster use Starwind, with no advice on what the actual problem may ever be.
The Datacore servers are HP DL380 G5s and they are Physical Servers dedicated as SAN.
Each server hasn an MSA70 attached to it and the Datacore software is configured as partneship between the servers
All volumes are mirrored.
