well as debug traces produced by the debug ppp multilink events command.

Release 12.4(6)T, but not with Cisco IOS Release 12.2(27)SBC2 or Release 12.4(4)T.

Workaround: Configure the ppp timeout multilink lost-fragment 1 command under the Multilink 
interface or the Virtual-Template interface corresponding to the multilink bundle.
