I've redistributed ospf to BGP and it works properly (quagga and cisco 6500 series) but sometime when a route is removed from OSPF cloud the BGP (cisco) doesn't update BGP advertisement to neighbors which it's peered so I've to clear bgp manually (not soft) , anyone face to this issue before? I can see the below logging at cisco as well :
I have not experienced quite this scenario and so can not speak from direct experience. But I can say that any time you get a traceback it is a sign of a software problem. I would guess that the solution to your issue may be a software upgrade (or downgrade) to a version that does not have this problem.
IOS SW fails to prepare the TCP segment that probably is the missing BGP update for the message you see.
Error message decoder says:
1. %TCP-2-INVALIDTCB: Invalid TCB pointer: [hex]
An invalid TCB is being used.
Recommended Action: If this message recurs, copy the error message exactly as it appears on the console or in the system log, contact your Cisco technical support representative, and provide the representative with the gathered information.

The only check I would do is to verify the amount of free memory on the router with
My idea about upgrading the IOS is that if you get a version of IOS that does not have this software bug, then the solution will be very fast.
I believe that the suggestion to check free memory was just a defensive suggestion to be sure that the error was not memory exhaustion leading to the error. For upgrading the image file the key things to check are the amount of flash and the amount of memory. The output of show version should clarify both of these variables.
