OL-13139-01

Open Caveats in Software Version 5.5.7

• CSCeh35923

Symptom: When you are trying to install the ACNS software on a Content Engine, DMA errors are

displayed.

Condition: This problem only occurs under the following condition:

a. You are trying to install the ACNS software image on a CE-7326.

b. You select Option 7 from the Installer main menu as follows:

Installer Main Menu:

1. Configure Network

2. Manufacture flash

3. Install flash cookie

4. Install flash image from network

5. Install flash image from cdrom

6. Install flash image from disk

7. Wipe out disks and install .bin image

8. Exit (and reboot)

Choice [0]: 7

Workaround: The DMA errors are displayed four to five times in sequence and then the normal

operation of the Content Engine continues without any user intervention.

• CSCei01668

Symptom: The firewall shows that there is an excessive amount of traffic coming from the

Content Engine over TCP port 8999.

Condition: This problem occurs if the Content Engine is on the outside of the firewall (connected to

the internet gateway router). The Content Engine is constantly attempting to reset the connections

to inside the firewall with a source port of TCP 8999 going to the NAT address of the clients.

Because the port translation timer has expired on the Content Engine, the Content Engine uses port

8999 to return the message to the client. Because there is no NAT address configured on the firewall

with the TCP port 8999, these messages fail at the firewall.

Workaround: Configure the following global configuration mode commands on the Content Engine:

ContentEngine(config)# http tcp-keepalive enable

ContentEngine(config)# tcp keepalive-timeout 60

ContentEngine(config)# tcp keepalive-probe-interval 60

• CSCei28716

Symptom: The system stops functioning and there are kernel core dumps.

Condition: This problem occurs rarely.

Workaround: No workaround is required because the Content Engine will reboot and work normally

after the reboot.
