Hi, I'm not sure if this is related at all to the vserver, but I can't figure out what's going on/wrong. I'm running # vserver-info Versions: Kernel: 2.6.22.19-vs2.2.0.7 VS-API: 0x00020200 util-vserver: 0.30.212; Dec 9 2006, 12:26:51 Features: CC: gcc, gcc (GCC) 4.1.2 20061115 (prerelease) (Debian 4.1.1-20) CXX: g++, g++ (GCC) 4.1.2 20061115 (prerelease) (Debian 4.1.1-20) CPPFLAGS: '' CFLAGS: '-Wall -g -O2 -std=c99 -Wall -pedantic -W -funit-at-a-time' CXXFLAGS: '-g -O2 -ansi -Wall -pedantic -W -fmessage-length=0 -funit-at-a-time' build/host: i486-pc-linux-gnu/i486-pc-linux-gnu Use dietlibc: yes Build C++ programs: yes Build C99 programs: yes Available APIs: compat,v11,fscompat,v13,net,v21,oldproc,olduts ext2fs Source: e2fsprogs syscall(2) invocation: alternative vserver(2) syscall#: 273/glibc Paths: prefix: /usr sysconf-Directory: /etc cfg-Directory: /etc/vservers initrd-Directory: $(sysconfdir)/init.d pkgstate-Directory: /var/run/vservers vserver-Rootdir: /var/lib/vservers In a vserver I'm running debian testing with # gdb --version GNU gdb 6.7.1-debian trying to debug php # php -c . -v PHP 5.2.3-1+lenny1 (cli) (built: Oct 3 2007 19:22:40) Copyright (c) 1997-2007 The PHP Group Zend Engine v2.2.0, Copyright (c) 1998-2007 Zend Technologies However I always get this: qa01:~# gdb php GNU gdb 6.7.1-debian Copyright (C) 2007 Free Software Foundation, Inc.

Does anyone have a clue if this is possibly related to vserver somehow? Or am I on the complete wrong track? thanks, - Markus
