Re: Deadlocks with Apache mpm worker and mod_jk

I saw that trail... hence some of the questions:
- why the error in particular with mod_jk (Rainer wrote once that jk module
use pthreads - is that different from other module)? are a few of these
errors actually really bad?
- is sysvsem a better Mutex to change to on newer Solaris 10 (hasn't the
sysvsem configuration been drastically improved since Solaris 8 aka 2004 -
eg. no /etc/systems entry required anymore).
