Bug#301965: apache-ssl segmentation fault when gracefull restart (SIGUSR1)
Package: apache-ssl
Version: 1.3.33-4
Severity: important
The apache-ssl package crash every sunday when the log rotate is executed. After some debug, it seems crash when we do a gracefull restart of the apache daemon : kill -USR1 or /etc/init.d/apache-ssl reload
see the trace log before :
