We have an 1841 router (version 12.4(25) IOS)and recently it has been kicking out the following errors:

.Jun  8 05:19:00: %SYS-2-BADSHARE: Bad refcount in datagram_done, ptr=634554D0,

Hello Jones,

traceback = software bug just to start

the error message decoder about %SYS-2-BADSHARE says:

%SYS-2-BADSHARE:

Bad refcount in [chars], ptr=[hex], count=[hex]

A reference count is used to track the usage of many data  structures. A function  increments the count when it begins to use a structure and decrements it  when it finishes. When the  count becomes zero, the data structure is freed. This message indicates  that when the count was  accessed, it was found to be negative which means that the data  structure will not be freed until the  system is reloaded.

Recommended Action: If this message recurs, copy the message exactly as it appears on  the console  or in the system log. Research and attempt to resolve the issue using  the tools and utilities provided  at
http://www.cisco.com/tac.  With some messages, these tools and utilities will supply clarifying  information. Also perform a search of the Bug Toolkit
http://www.cisco.com/pcgi-bin/Support/Bugtool/home.pl.  If you still require assistance, open a case  with the Technical Assistance Center via the Internet
http://tools.cisco.com/ServiceRequestTool/create,  or contact your Cisco technical support  representative and provide the representative with the gathered  information. Include the stack trace.

means that a packet that is held in a buffer for process switching at the moment to be examined by main cpu has been "lost" in memory

This is cleary a software bug.

Hope to help
