----------------------------------------

Yes, apparently prefork is used by default on RedHat.

> One of our universities observed some strange behaviour of the native.log. With RedHat 5 they only hardly get any entries besides the ones below when starting the SP:
> 	2012-11-04 20:27:12 INFO XMLTooling.Config : xmltooling 1.5.1 library initialization complete
> 	2012-11-04 20:27:12 INFO Shibboleth.Config : shibboleth 2.5.0 library initialization complete
> 	2012-11-04 20:27:12 INFO Shibboleth.Config : shibboleth 2.5.0 library shutting down
> 	2012-11-04 20:27:12 INFO XMLTooling.Config : xmltooling 1.5.1 library shutdown complete
> 	2012-11-04 20:27:12 INFO Shibboleth.Config : shibboleth 2.5.0 library shutdown complete
> 	2012-11-04 20:27:12 INFO XMLTooling.Config : xmltooling 1.5.1 library initialization complete
> 	2012-11-04 20:27:12 INFO Shibboleth.Config : shibboleth 2.5.0 library initialization complete
> 	2012-11-04 20:27:12 INFO Shibboleth.Config : reload thread started...running when signaled
> 	2012-11-04 20:27:12 INFO Shibboleth.Config : reload thread started...running when signaled
> However, there should be more entries than this (in my centos 5 installation about 191 INFO entries)
> So, they added <InProcess logger="native.logger"/> to shibboleth2.xml, which by default is not included.
> This then results in the following CRIT entries:
> 	2012-11-04 20:55:04 CRIT XMLTooling.Logging : error in file permissions or logging configuration: exception creating appender: failed to open log file (/var/log/httpd/native.log)
> 	2012-11-04 20:55:04 CRIT Shibboleth.Config : failed to load new logging configuration from (native.logger)
> However, the file /var/log/httpd/native.log exists with root:root 644. It also does not play a difference if the native.log is written to /tmp/. Same result. Also, in this case the log rotation does not work and the log file grows larger and larger. After a while one will find exclusively entries like these:
> 	2012-11-07 13:46:17 INFO Shibboleth.Config : loaded XML resource (/etc/shibboleth/shibboleth2.xml)
> 	2012-11-07 13:46:45 INFO Shibboleth.Config : reload thread started...running when signaled
> Something else they observed are many entries like:
> 2012-11-06 04:25:46 WARN Shibboleth.ServiceProvider [27347] shib_check_user: can't export assertions without an exportLocation Sessions property
> Is it justified to make these WARN entries if exportAssertion is not used at all?
