Chapter 3 Corrected Problems BEP Corrected Problems This table contains a brief description of each Change Request (CR) completed for this CVX switch release for the BEP. CR Number Category Release Note Q00047989 BEP The CVX BEP no longer goes into event logging loop when secondary BEP fails during file syncing. The event logging loop depleted BEP memory and caused it to crash with “DMM unable to allocate memory” panic reason.
CVX Multi-Service Access Switch 4.1 Release Notes CR Number Category Release Note (continued) 149219-1 FEP The FEP no longer crashes when more than three DNS servers are configured. Previously, there was no limit enforced by configuration, which caused memory corruption. Now, the number of DNS servers has been limited to three. If more than three DNS server are configured, error messages are written to the event logs while the system is rebooting. Valid container IDs are 0, 1, and 2.
Corrected Problems CR Number Category Release Note (continued) 145417-2 FEP The FEP no longer crashes in the Ethernet driver code. The problem occurred when two processes tried to access a structure at the same time, causing memory corruption. 145307-3 FEP The FEP no longer crashes during FTP due to a problem with the TCP idle timer. The socket level timeout was reduced to one minute.
CVX Multi-Service Access Switch 4.1 Release Notes CR Number Category Release Note (continued) 143183-2 FEP The FEP no longer crashes with a machine check exception during local authentication due to a null pointer. 143153-2 FEP In a failed session, the CVX now passes the actual user name in the Accounting Stop packet. It had previously been passed as an unknown user name. 143126-2 FEP The FEP no longer crashes with a machine check exception while processing a RADIUS RPC message.
Corrected Problems CR Number Category Release Note (continued) 137570-1 FEP Active and inactive DVS sessions are now recognized correctly in DVS-specific CLI commands. Previously, with multilink bundles, all sessions were shown under the dvs active CLI command as inactive when any of the slave links were terminated. 137568-2 FEP Multilink connections no longer fail after more than two links with bogus VPOP. 136765-2 FEP The show modem command correctly identifies available commands.
CVX Multi-Service Access Switch 4.1 Release Notes CR Number Category Release Note (continued) 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.
Corrected Problems CR Number Category Release Note (continued) 144383-3 MAC The maximum number of terminated L2TP sessions kept in the log buffer has been reduced from 256 to 128 to increase available memory. 144323-3 MAC The MAC no longer crashes due to race conditions in queing routines while under a heavy ClearTCP load. 144252-3 MAC A timer has been added before the end of a ClearTCP session to give enough time to tasks to perform a proper cleanup.
CVX Multi-Service Access Switch 4.1 Release Notes DAC Corrected Problems This table contains a brief description of each Change Request (CR) completed for this CVX switch release that affects the DAC. CR Number Category Release Note Q00046695 DAC Individual E1 will no longer bounce and go into red alarm.
