CR00021342 BGP 2 A small memory leak was occurring when receiving BGP update messages.
This issue has been resolved.

CR00021491 DVMRP 2 When DVMRP had pruned an incoming multicast stream, if that stream
continued to be transmitted and pruned correctly, after 24 hours the
downstream DVMRP neighbour could stop successfully pruning that
stream. At this point the downstream neighbour would be receiving the
traffic on the interface even though it had no downstream receivers. This
issue has been resolved.
YYYYYY––YYY
CR00020593 Firewall 2 When using multiple firewall policies, TCP connections created across the
policies would have any TCP options (such as timestamps or window
scaling) stripped out of the SYN packets. This could cause slow downs or
other problems for programs that rely on those TCP options being present.
This has been resolved—the TCP options will no longer be stripped from
the SYN packets in this case.
Also, the RFC1323 TCP window scaling option, if present, would not be
correctly applied to FTP data connections (FTP connections on port 20),
resulting in low throughput for FTP file transfers. This issue has been
resolved.
YYYY–Y––––Y
CR00020643 Flash file
system
2 An error in the flash file rename code could occasionally result in flash file
system header corruption, leading to flash file system inconsistencies.
This issue has been resolved.
YYYYYYYYYYY
CR00020677 IPsec 2 Previously, one of the memory buffers displayed in output of the command
show buffer scan was periodically increasing, because of an IPsec
issue.This issue has been resolved.
YYYY–Y–––––
CR00020700 WAN load
balancing
2 Previously, AR750S and AR770S routers required a special feature license
for WAN load balancer. This issue has been resolved. A license is no longer
required for these routers.
