Does the switch show any errors on the port before it stops communicating? "Show Logg" on switch to see if it is giving any errors. Are you using WCCP or inline for communication? Is it the management port (WCCP port) or the inline port that is losing communication? I was on 5.1.1c with no issues before I went to 5.3.1, never went to 5.1.1d
If you think it is a version issue, do a quick upgrade to see if it resolves the issue. It is already unreliably bouncing, an upgrade will not hurt any more. Or, even a downgrade to what you were running before 5.1.1.d. Did the issue begin right after you upgraded to 5.1.1.d? Is that why you believe it is the code version causing the issue?
