Appendix A Troubleshooting
Streaming and Playout Issues
The CServer returns the same completion code, so the same error is returned in the announce
message. In this case, the content does not stream at all. The play request and play response
are separated by about 10 to 15 seconds, instead of the typical subsecond separation. This is
because of the ARP timeout process the CServer is going through to reach the destination. After
stream response fails, the CServer calls back with the completion code of 3, which causes the
“error reading content data” message.
Action 1: Check that the interfaces involved in the streaming are up and operating at the correct speed.
Using the CDSM GUI, choose Monitor > Server Level > NIC Monitor, choose the IP address
of the server, and verify the participating interfaces are up and operating at gigabit Ethernet
speeds For more information, see the “Configuring the Interfaces” section on page 4-109.
Action 2: Set up a stream to play to a multicast address.
If this is successful, then there is a network problem, which is either a default gateway or
unreachable remote client. You can verify whether it is successful by looking at the
/home/stats/ifstats information.
Action 3: If streaming to a multicast address is not successful, check that the Vaults can be reached.
Check the /arroyo/log/protocoltiming.log.<date> log file for the number of reachable remote
servers. Additionally, if there is a cache-fill issue, you will see a large megabit value for the
re-xmit buffer.
You can also check the /arroyo/log/c2k.log.<date> log file for any unreachable Vaults.
Tuning Failure
Cause 1: Fail to tune error message (Error 104).
A “fail to tune” error message (Error 104 in the /arroyo/log/streamevent.log file) occurs when
the CDSM starts a stream, but the stream fails to reach its destination.
Action 1: To verify the ARP table, enter the arp -a command.
Action 2: Verify there are no network problems; for example, reachability, network partition, and so on.
Action 3: Look for timeout intervals.
Look for characteristic 10 to 30 second timeout intervals between the stream setup and the
stream destroy event messages in the /arroyo/log/c2k.log.<date> file.
Restarting the ISA Services
If it is necessary to restart the ISA services, then enter the following commands:
$ /home/isa/IntegrationTest/stop_all
$ tail –f /arroyo/log/ns_log
$ /home/isa/IntegrationTest/run_isa
Poor Video or Audio Quality
When content is streamed to a client device, if there is no video picture displayed on the client device
and the audio is working fine, use the following troubleshooting methods:
• Verify that the source is working properly and that the original content is of good quality.
