iscsi issue conn_close(101) in the target

Hi;

I have this scenario:

Centos 6.3 fresh install, configured has iscsi target.

Proxmox 2.2

Whent try to conect one iscsi target from the webIU, the log/messages from centos make a recursive error every 9-10 sg.

teststorage tgtd: conn_close(101) connection closed, 0xb7e258 1

But, if added the iscsi iniciator for de cmd, no problem happends.
I thing are some bug in the system to make the iscsi conections in the webIU, somebody have ant solution ?
