CentOS

Answering my own question this is a great link describing in detail how the tool works.

The VM hasn't crashed since but I'm not 100% sure it's fine because there hasn't been that much asterisk traffic since.

I switched the traffic to a different VM with more swap running a fully updated system :

[code]cat /etc/redhat-release CentOS release 5.6 (Final)[/code]
[code]uname -rv 2.6.18-238.5.1.el5xen #1 SMP Fri Apr 1 19:35:13 EDT 2011[/code]

Lets see if this will solve the problem.

Thanks for the helpful comments :) @TrevorH The VM crashes and the call trace is from the VM. The host is running fine as well as other VMs that this host is running. @pschaff I don't want to update yet because it's a production server running asterisk and I want to be certain this is the problem, b...

Hi, I'm using a CentOS VM running on Xen and it sometimes crashes under heavy load. The CentOS version is : [code]CentOS release 5.3 (Final)[/code] The kernel : [code]2.6.18-128.1.10.el5.xs5.5.0.51xen[/code] The Call Trace after the crash looks like this : [code] [<ffffffff802bc9d1>] out_of_memory+0...

Ok. Thanks a lot for help anyway.

Thanks for the reply. What do I need to enter there to forward ports 6666-6669 udp and tcp ? I mean what is the syntax because I couldn't find it in this GUI help ?

Should something like 6666-6669:udp_tcp work ?
Or the same using two entries 6666-6669:tcp and 6666-6669:udp ?

Hi, How is it possible to open a range of ports in the Centos 5.5 default firewall and make it permanent ? For example if I wanted to open ports ranging from 6666 to 6669 for incoming tcp and udp packets? Preferably using some inbuilt GUI or CLI tool so that I don't have to install any additional so...

Yes I'm perfectly aware that SElinux and firewall are totally different things but thanks for additional clarification :-) it's just that this tool allows for some configuration of both. I don't deny that most likely I locked myself out of the system by my own mistake but still it happened. I'm glad...

Hi I'm using CentOS 5.5 fully updated. I wanted to ask if anyone is using this tool and if yes what is the experience. I'm particularly interested in it because it's more user friendly than manual editing of iptables rules and it's possible to run it without X running, which is something I might nee...
