Linux "grsec: Segmentation fault..." - TFS 0.3.6 crash

[MeNi]

Hi,

I have a problem, my server (TFS 0.3.6) on my ded. server (kimsufi.pl / 4GB Ram, 4x2.4CPU / 100Mbps / Debian 5.0 x32) sometimes is crashing. When it happens, there are such errors:

In dmesg: (this ip 83.24.119.89 is my PC ip, i was online on server when it happened)

What is reason of that? How i can fix it?

 

[MeNi]

bump, what is reason of this error & how to fix it?

 

[stian]

Hmm, seems like you installed hardened debian and forgot to change the rule set.

 

[MeNi]

Hmm, can you explain what rule set do you exactly mean and how to change them?

 

[stian]

I'm to lazy to write a ruleset for you.

Gentoo Linux Documentation -- Gentoo Grsecurity v2 Guide got some nice info you can use.

 

[MeNi]

This is whoole documentation for grsec, I don't get it - I am begginer in Linux OS, could You tell at what part i should focus fixing it, as I have not so much time, I am starting project in couple of days and thoose crashes suprised me when i was sure evrything is good..

 

[stian]

Install something else then hardened distros then. Ubuntu 9.10, way easier.

 

[MeNi]

I instaled Ubuntu 9.10, but it seems that there is grsecurity too and it is crashing sometimes.c What can i do? (I have dedicated server from kimsufi.pl)
