bad frame in signal deliver frame

[haschi]

Hi!

Hab seit heute folgendes Problem.

Der Server läuft soweit ganz flüssig. Nur heute, nun schon zwei mal, schmiert scheinbar der Apache ab. in kern.log steht folgendes. Nur ein kurzer Ausschnit, fängt ab da an bis er nicht mehr erreichbar ist bis zum Reset.

Apr 10 22:09:08 freunde-server kernel: apache2[2257] bad frame in signal deliver frame:0000007fbf7ff348 rip:2a97731a86 rsp:7fbf7ff790 orax:ffffffffffffffff

Apache2 : bad frame in signal deliver frame: ...

Hello,
I do have the same problem as you with my Apache2 servers.
I have a 5 apache2 servers' farm and I saw the same error message about 10 times a day on each server.
-I use a Dnat balancer running iptables
-My farm is a Linux Sarge AMD64.
-The servers are Dual Opterons with 8G RAM.

Please, does anybody know anything about this strange annoying message.

PS: Could you reply in English please (I am French and do not understand your language) thanks by advance.

This rather cryptic error message means, that the program in question (apache) corrupted some data on the program stack during its execution and therefore the thread was terminated.
If you want to find out what caused the error message it would probably be helpful to have a reproducible test case for it: Take a look at the access.log file and try to find out what URLs were being accessed while the error shows up in the error.log (allow +- a second). Then access those URLs in the same manner until you see more error messages in the log files (-> tail -f error.log).

I'm not familiar with the Debian product time line, but the format of the error message indicates that you're using a kernel from the 2.4.x series which is quite dated. This makes me wonder which version of the apache and the C-library you're using. If they're from the same vintage as the kernel it might be rather pointless to try to locate this error, because so many other bugs have been fixed in current versions of both the apache and the various libraries it uses.

Apache2 : bad frame in signal deliver frame: ...

You are right,
I was using a 2.6.8 Kernel with Apache 2.0.54 / PHP 4.3.10-16

So I did some more testing and manage to reproduce the error.
The error appends when browsing any page with Firefox and a particular set of cookies (Once deleting the cookies all turns right.)
Then, I 've take a look at the set of cookies and saw noting particular.
The response is immediate and the page is blank without any client error.
Just a segfault in the apache error log.
In this last test I ran a kernel 2.6.8 with apache 2.2.3 / 4.4.4-8+etch4 (out of the cluster on a standalone server)

There is the log:

Thanks for your answer, I will have some more testing now.
