[asterisk-users] Asterisk using 200% CPU and then crashing...
We have a customer that has Asterisk 1.4.12.1, Zaptel 1.4.5.1, Asterisk-Addons 1.4.3. running on a Dell Poweredge 1900 server (Dual Core Xeon, 4gb RAM, 500gb Raid 5). Until a month ago they had two TE120P cards and everything was working fine. Since they needed to add a third E1 line we decided to change one of the TE120P cards with a TE210P. After the change we had a couple of crashes (server completely locks up). At first we thought we had a defective card so we changed it but kept having the same problem. We have tried a TE411P, a Sangoma A104x (PCI express), an Openvox D210P and D410P and still the server crashes about three times a week. I can see the Asterisk process go from around 10% usage to 100%, then 200% and the server hangs after that. Why would inserting a multiport card affect Asterisk and the server? How can I debug this situation? I do not have enough slots to insert three single cards of the same type so I need the multiport card to work. When Asterisk goes above 100% it will start ignoring commands you issue on the CLI but calls keep coming and going. At this moment I have to watch the server all day and if it goes above 100% I restart Asterisk when we have a low call volume. Obviously I cannot keep doing this forever. Could this be a problem with the Server? Maybe a Kernel problem? So far all I have been willing to do is put acpi=off as a parameter on the kernel because I read that sometimes ACPI causes problems. Same problem still. I have not been able to determine a pattern to when Asterisk will start using more CPU, sometimes it will go four days of heavy use without a problem and then start acting up on a Saturday with very few users. Any ideas will be appreciated. -- Telecomunicaciones Abiertas de México S.A. de C.V.

If you still have the issues, you'll know to look elsewhere.

I recently had the same problems. Just that wasnt't related to installing any new hardware.

The server is running CentOS 5 with all upgrades applied. I have glibc-2.5-12 installed. If I could only test the individual cards for two days before having to install the Sangoma A104x again and in those two days I did not have any problems. We are not using IAX at the moment so I can disable it from modules.conf the next time I have to restart Asterisk. Right now we have two E1 links to the phone company and one E1 link to a Panasonic PBX. There are around 40 SIP phones connected to the server. Six of those phones are used for a small call center with one queue. All E1 links use Unicall. -- Telecomunicaciones Abiertas de México S.A. de C.V.

The Dell PowerEdge 1600 is listed on http://www.digium.com/en/docs/misc/compatibility_notes.php Not sure about the 1900. However your problem might be completely unrelated to any Dell specific issues.

Your version of glibc screams out as the possible problem.
