Summary: apache2 ssl does not work on xen domu host Product: Xen Version: 3.0.2 Platform: x86 OS/Version: Linux-2.6 Status: NEW Severity: normal Priority: P2 Component: Unspecified AssignedTo: xen-...@lists.xensource.com ReportedBy: fcu-...@no-way.org

I'm trying to get apache2 and ssl running in a domu. The config i'm using works fine on a debian sarge on a dedicated machine. But with debian sarge on the domu machine, the http process serving the request crashes as soon as it gets an ssl request. Non-SSL works fine, so do many other services (mysql, powerdns, qmail, ...)

Apache is 2.0.58 self-compiled, however the official debian packages behave the same way.

I run Xen version 3.0.2-3 (Debian 3.0.2+hg9697-0bpo1), with kernel 2.6.16.27 with hg9697 patch. I tried 2.6.16 using an older patch as well. I can reproduce the bug in another domu on another host.

I tried using the stock glibc6 with /lib/tls moved away, and a patched glibc 2.3.2 which support tls and xen, behaviour is the same.

apache2 uses the prefork worker, threaded worker is the same.

Apache2 Backtrace:

This GDB was configured as "i386-linux"...Using host libthread_db library "/lib/tls/libthread_db.so.1".
