CVX Multi-Service Access Switch 4.1 Release Notes
148123-1 MAC The problem of the MAC crashing while bringing up 1,344 L2TP calls was
corrected by masking interrupts before checking the value of a session
pointer.
146882-1 MAC The MAC no longer crashes due to queuing race conditions which caused
over-allocation of ClearTCP sessions. ClearTCP was creating new sessions
after the maximum number of sessions had already been reached on the
MAC.
146872-1 MAC The MAC no longer crashes due to a watchdog timer expiration. This was
caused by receiving prolonged bursts of data from the SCC. It was
corrected by adding a limit on the number of frames to be processed in a
continuous transmission.
146672-1 MAC The MAC no longer hangs while receiving data during error conditions. The
hang condition caused Ethernet frames to be discarded.
146304-1 MAC The MAC no longer crashes with an "ipstub session exhausted" error. The
number of sessions was extended from 256 to 408. Also, the allocation and
freeing of new sessions are now synchronized to avoid a race condition.
146159-2 MAC The MAC no longer crashes due to bad packet length calculated by the
Compression Control Protocol (CCP) decompressor.
146042-1 MAC Modems will no longer hang and cause repeated "Fail to Awaken"
termination codes. Modems were hanging because the IOP image was
issuing modem commands without waiting for the modem to be fully
disconnected after terminating the previous call.
145738-1 MAC Multiple IOP reboots in L2TP environments no longer cause the MAC to
crash. L2TP failed to fully release the MAC’s memory when an IOP crashed
or was manually rebooted. This condition depleted the memory pool on the
MAC, eventually leading to the crash.
145341-1 MAC VJCompression of packets with identical IP identification fields is now
handled properly. Users of Prodigy’s Odigo 3.0 instant messaging no longer
have problems contacting the server.
145241-1 MAC Termination causes are correctly encoded in the MIP DVS tunnel
deregistration, link down packets, and accounting stop requests.
145096-2 MAC The MAC no longer crashes due to memory allocation failures while
creating an IP access list.
144827-3 MAC The MAC no longer crashes after more than 64 DVS multilink sessions are
closed.
144661-3 MAC ClearTCP now supports up to 204 sessions for double-density MAC cards.
144415-2 MAC The CVX no longer writes multiple core dump files for a single failure on a
MAC. Events are now logged for crashes and core dumps.
