openVZ and FS: core dump!?
hi all, at the moment we are playing arround with openVZ (container) and freeswitch. as far as we have read, openVZ and fs are working quite well together. but we are getting a lot of fs core dumps, when testing. we are using actual versions of fs, which are running very smooth on normal/real servers without openVZ. the only information we get out of the core dump is: "Program terminated with signal 6, Aborted." are there any settings or things, which have to be looked at, when running fs in an openVZ container? thank you for your help! dennis
for me it works very well. I used to run it on Openvz installed as rpm on a centos 6, I've switched to a Proxmox install (that's based on Debian 6 Squeeze, and gives you management of KVM machines too, in addition of OpenVZ containers) and I'm very happy. -giovanni On Mon, Sep 24, 2012 at 10:10 AM, Dennis <odermann@googlemail.com> wrote:

we are using proxmox too. are there some settings in proxmox or fs, which might help? we are running ubuntu 64bit...
ubuntu64 template I assume. No special settings here, just be sure to give it (the container) enough resources (eg: memory) Also, we use the debian 6 template (debian 6 is used by FS dev as platform, other platform being centos 5) but I would exclude is a template problem. Check the UBC counters if you got some overrun of limits. -giovanni On Mon, Sep 24, 2012 at 10:37 AM, Dennis <odermann@googlemail.com> wrote:

thank you for your help! perhaps we should try debian instead of ubuntu (although all our fs servers are running ubuntu without any problems)? we tested by giving the container 2 cpu cores and 2 gig of ram. do you think the 2 gig ram are not enough, so that fs core dumps because of this? i don't know what ubc counters are and how they are used, but i will try to find out.

I would say it's irrelevant, ubuntu or debian. Crashes not from here

it depends on traffic, registration, etc etc etc

in proxmox web interface, you have a tab UBC, bot for the host and for the containers. You can have a look in those tabs, while containers are running, to see if you have allocated enough resources. Also, are you on the "stable 1.2" git branch? ( http://wiki.freeswitch.org/wiki/Installation_Guide#Selecting_version ) -giovanni

we are testing with 1.3.0 + git. this version is running withour any problems on another fs server. i fount the UBC tab in proxmox. failcnt is 0 and it looks, as if the limits are set high enough. very strange, we tested proxmox on two different servers with the same result. so the hardware shouldn't be the problem.
1.3.0 is the development version, it can have problems, at times. btw, maybe you are at a different revision between containers and other servers. Anyway, the policy for which code base to use is changed! Before it was the git trunk (you are using it), now (since a couple months) is the stable git branch. Please refer to my previous mail. Hope this helps -giovanni On Mon, Sep 24, 2012 at 11:28 AM, Dennis <odermann@googlemail.com> wrote:

we nearly never use branches, because often things are not working the way we need it or other important features are added meanwhile. therefore we often use newer versions, we test them and if everything is working, we use them. perhaps we should try fs 1.2 with proxmox to make sure, there are no problems in the newer fs versions with proxmox. but as ia wrote: we currently running fs 1.3 without any problems on other servers.
