Nginx with SSL problems on Sparc

Server NGINX
1

We are using nginx on Sparc, it’s Debian Linux stable

Linux Sunium 2.6.26-2-sparc64 #1 Mon Jun 21 15:45:39 UTC 2010 sparc64
GNU/Linux

We have Apache2 on port 88 as a single upstream, nginx is serving HTTP
and HTTPS as well (ports 80 & 443).

HTTP is working great, however HTTPS has some problems - every say 5th
request is failed and empty page is served. Nginx logs are full of these
error/warning messages:

There are different signals, different errors, I tried to extract the
most descriptive pattern.

I know this is probably platform dependend, since we are using on many
Intel servers without any problem. But my question is what to do next?
Should I debug, or strace this or just simply send this to Debian
package maintainer?

I tried to upgrade nginx, OpenSSL, libssl, I tried several different
combinations, but with no luck.

Thanks for any help or clue

What nginx version do you use ?

I double check (again) the problem and it show up on these versions:

nginx_0.6.32-3+lenny3_sparc.deb
nginx_0.7.67-1_sparc.deb

Unfortunatelly I have not found SPARC version of nginx not affected with
this :frowning: But I tried.

We switched back to Apache SSL, which I’m completelly not happy with.
SSL configuration is messy, it’s big & fat, and also tens if not
hundreds of our machines they all use nginx, except this single one.
Yes, it is the only one on SPARC, all others are Intel:)

Thanks
