hi,

did you ever find anything more about this segfault? if its really related to the secure download module i would be interested in fixing it.

i agree, to be able to help you i will need more debug info like a backtrace. please do not forget to also include your config file. you also mentioned that those segfaults suddenly started, do you know if anything changed, in the config or wherever at this time?

Probably the best way to start is to create the coredump / backtrace ( http://wiki.nginx.org/NginxDebugging ).

Also as that is a third-party module tried to contact the author directly (if you are sure the module is the cause)? (the first step most likely will be needed anyways unless the module is broken in general with the nginx version changes).

Hi;

I've compiled in Secure Download to nginx 0.7.65 & 0.8.39 and whenever I make use of the Secure Download directives, the processes keep segfaulting.

[code] [size=small]Jun  3 04:04:03 localhost kernel: nginx[23299]: segfault at 1 ip 00000000004204ad sp 00007fffbda98228 error 4 in nginx[400000+6a000] Jun  3 04:04:03 localhost kernel: nginx[23298]: segfault at 1 ip 00000000004204ad sp 00007fffbda98228 error 4 in nginx[400000+6a000] Jun  3 04:04:03 localhost kernel: nginx[23285]: segfault at 1 ip 00000000004204ad sp 00007fffbda98228 error 4 in nginx[400000+6a000] Jun  3 04:04:03 localhost kernel: nginx[23291]: segfault at 1 ip 00000000004204ad sp 00007fffbda98228 error 4 in nginx[400000+6a000] Jun  3 04:04:03 localhost kernel: nginx[23301]: segfault at 1 ip 00000000004204ad sp 00007fffbda98228 error 4 in nginx[400000+6a000][/size] [/code]

The module creator says it's been tested in 0.7.61, but we had it working for a period of time in 0.7.65 before the segfaults started, seemingly out of nowhere.

Does anyone have any idea what could be causing this?

I'm using Fedora Core 12 with bonding across three 1 gigabit interfaces. The server regularly pushes out 2.5+ gigabits of bandwidth - we have a good idea of what we are doing over here so technical responses are welcome.

Thanks!

Richard
