Hello Philip Martin and Nico Kadel-Gracia, thanks a lot for your support. It seems that it was really a problem. I tried the hooks (unchanged as I have saved them inbetween in subversion) today at a different machine (with more memory) and there all hook scripts work perfect. The Apache WebDav configuration is on both machines identical.
One last point, which I still not understand. In the link you sent, I saw that you got "Cannot allocate memory" in the apache log. I saw at our machine (where the problem occurred) no error messages in the apache log. In the /etc/apache2/apache2.conf I configured a specific log file for my tests (ErrorLog /var/log/sbox_log/error.log) and Log level "debug" (LogLevel debug) . Log info was written to this Log fIle but no information, why the execution of the hook scrip failed. Strange. Again thanks a lot for your support.

I believe the "Failed to start" message means that Apache is failing to fork a child process and is not getting as far as attempting to run the hook script. One possibility is this memory problem: http://mail-archives.apache.org/mod_mbox/subversion-dev/201211.mbox/%3c87bof1nqcn....@ntlworld.com%3E in which case the solution is to allocate some swap or reduce the cache size. Run "strace -f -p <NNN>" on the apache process and look for the clone() and execve() calls. That will confirm whether or not apache is forking and attempting to run the hook. -- Philip Martin | Subversion Committer WANdisco // *Non-Stop Data*
