  Target Milestone: ---

When apache is running for a long time a systematics segfault appear on log_io
mod. 

This behaviour appear on several severs and seem systematics. 

An apachectl graceful can't block this issue, I must perfom an apache restart
in order to avoid this bug. 

Here is the error message displayed in kernel logs : 
kernel: httpd[50551]: segfault at 7fc0b9b51b60 ip 00007fc0b9b51b60 sp
00007fc0af7fda38 error 7 in mod_logio.so[7fc0b9b50000+2000]

The at and ip value are already the same on all occurences.
