Hello,

Nobody answered. I answer to myself...

Other than this, I noticed log lines like :

**************************************************************

detected/avoided: apr_proc_mutex_lock failed. Attempting to shutdown

Well, as I'm having performance issues with horde... The new version 
(horde 3.3.6/imp 4.3.6) runs almost 1,5 times slower than previous one 
on a very recent machine (Dell R710 w dual quad core procs and 16 G RAM 
and Solaris 10). Users takes near 15 s to login. Trying to tune this, I 
felt into some people suggesting to compile apache with the worker mpm 
instead of prefork. But it seems that the configuration (worker 
mpm/https/solaris 10) isn't ideal.

Recompiling apache with the traditional prefork mpm solved the issue.

But the performance issue remain there. I'll try other things.

Thanks
