Lunchbox-type PC as small server?
by Fred 07 Mar '09

07 Mar '09

Hello I'm looking for a small, lunchbox-like PC to build a small-form factor CRM server to sell to small companies. Ideally, it should have one PCI slot so that I can stick a voice card to connect to an analog phone line and run FreeSwitch as well. I like Asus' EeeBox (www.asus.com/products.aspx?l1=24&l2=165) but it doesn't have room for a PCI slot, and I'm concerned about its performance. I also like stuff from MiniITX (www.mini-itx.com) , but they're a bit pricey, and might also not be fast enough to act as a server. Are there brands/models you think I should look at? Thank you.

FS crashed
by Pablo Hernan Saro 06 Mar '09

06 Mar '09

Hi there, A few minutes ago, one of my FS servers crashed during normal usage (no heavy load). The hardware is Dell 1950, if you need further details please let me know. What I found on my /var/log/messages is the following: Mar 6 14:30:49 konference01 kernel: freeswitch[23798] general protection ip:7fae144e222f sp:40750540 error:0 in libc-2.7.so[7fae1446d000+14c000] I'm not familiarized with this kind of errors, but as far as I know a "general protection" occurs when a process tries to access a memory address not owned by it (probably I'm saying bullshit). The FS log does not report anything abnormal. I'm running FS svn rev 11279. Does anyone know what could happened? Thanks Pablo

Re: [Freeswitch-users] Setting External IP
by Kristian Kielhofner 06 Mar '09

I've never tried it but Linux routing should be able to help you with this. Create a new profile with the different address. Make sure the aliases on your network interface have a /32 netmask. Create a static route to that peer using the right outbound interface/address. Anything more than this will require iptables/iproute ip policy routing foo. Hopefully you can avoid all of that... -- Kristian Kielhofner http://blog.krisk.org -original message- Subject: [Freeswitch-users] Setting External IP From: "Nik Middleton" <nik.middleton(a)noblesolutions.co.uk> Date: 03/06/2009 6:05 AM Hi Guys, In External.xml in sip profiles I have <param name="ext-rtp-ip" value="$${external_rtp_ip}"/> <param name="ext-sip-ip" value="$${external_sip_ip}"/> Can I override these for a given gateway profile?

16 threads didn't exit
by Cavalera Claudio Luigi 06 Mar '09

06 Mar '09

Hello list, I'm trying to track down a seg fault issue with a fs Revision: 11489 Here is the backtrace pastebin: http://pastebin.freeswitch.org/7009 but before digging the dump I would like to understand: am I the only one having error like this in fs console: "Error in my_thread_global_end(): 16 threads didn't exit" I'm asking this because googling around did not take me to much relation between this error and fs. In fact as you can see the error does not have the usual fs logging format with date time and logging level, it's just a yellow line printed out in console. It seems to me related on php and mysql from what I've read here http://forums.mysql.com/read.php?10,153077,206930#msg-206930 It's possible that my fs segfaults not because of this error at all, but I just wanted to inform you asap in case someone could face similar issues. I've enabled crash-protection in switch.conf.xml although I'm not sure what it does.

Hung Channels (SVN Rev 10231)
by Eric Liedtke 06 Mar '09

06 Mar '09

Greetings, I've been using FS in production on this rev (I realize it's pretty far behind current) and it's been running well, save 1 issue. The basic setup is an SBC , 2 GiG-E ports, 1 public , 1 private. I have 2 sip profiles created , 1 per ip interface. This is being used to terminate traffic to a provider so calls are only 1 direction. They come into the private side profile, get routed via dialplan to the gateway defined in the external profile and on to the vendor. Pretty simple. I have noticed that under load (50 or so cps with ~800-900 bridged calls up) that over time some channels on the public side seem to get "stuck". Due to the nature of how this is being used , I would expect both sip profiles to show the same number of channels in use any time i do a 'sofia status' ( or at least be within a channel or 2 of each other). However after a day of heavy use I had a disparity of ~250 channels. These extra channels also seem to put some continual load on the 'system cpu' as well , reported via top. Of course due to the load on the box I have to keep logging turned way down. So I've been trying to troubleshoot it as best I can. Last night I grabbed a core file and started in with GDB today. I found the 120 or so threads that represented real active calls when I took the corefile, I also found ~250 threads that appeared to be stuck in the CS_NEW state. The backtraces on all of them looks the same, annotated below. I walked through the code path by hand , based on the bt's and I don't see how this could be happening unless it's a locking issue. But as far as I can tell each session has it's own mutex defined in the switch_core_session_t struct, so I wouldn't think they would be stepping on each other. I also would have expected if it were something of a deadlock nature it would stop processing calls all together. I grabbed the commands from the .gdbinit (super handy btw!!) and have been trolling through the variables to try to ascertain something about why these threads seem to be stuck, but am not having much luck even coming up with a scenario to try to replicate the issue. If anyone has any pointers as to where I might look next it would be greatly appreciated. We will be updating to the newest release soon, however I was hoping to nail down what is going so I can systematically replicate it and verify by testing in the lab that it is fixed , rather than just pushing the new release to produvction and hoping.

Newbie's installation: Can't start FS at boot
by dynaguy 06 Mar '09

Hello, I am a newbie to FS and I want learn it. So I setup a Centos 5.2 (fresh install) and followed the instruction on the wiki installed the new Freeswitch v1.0.3. After the installation I can start FS by issus command "/usr/local/freeswitch/bin/freeswitch". After that I copied freeswitch.init.centos5 to /etc/init.d/freeswitch and chmod it to 755. Reboot the server and FS is not running. If I try the start up script: [root@localhost build]# /etc/init.d/freeswitch start Starting freeswitch: [ OK ] [root@localhost build]# /etc/init.d/freeswitch status freeswitch dead but subsys locked Did I miss somthing here?
