Summary | 0007669: httpd crashes if mod_gnutls and mod_php is loaded while reload http | ||||
Description | If I install httpd, php and mod_gnutls, httpd dies while reloading httpd. Version-Release number of selected component (if applicable): httpd-2.4.6-18.el7.centos.x86_64 (from CentOS-Base-Repository) mod_gnutls-0.5.10-13.el7.x86_64 (from EPEL-Repository) php-5.4.16-23.el7_0.x86_64 (from CentOS-Base-Repository) | ||||
Steps To Reproduce | 1. Install httpd-2.4.6-18.el7.centos.x86_64 and php-5.4.16-23.el7_0.x86_64 from CentOS-Base-Repo: Step 1a) Start Apache 2.4: # systemctl start httpd.service Step 2b) Ask status of httpd: # systemctl status httpd.service Step 2c) Reload apache-config: # systemctl reload httpd.service I can do step "2c" many times, there's no problem- everything works as I expected! 2. Install mod_gnutls-0.5.10-13.el7.x86_64 (from EPEL-Repository) 3. Reload apache-daemon: Step 3a) Restart Apache 2.4: # systemctl restart httpd.service Step 3b) Ask status of httpd: # systemctl status httpd.service # systemctl status httpd.service httpd.service - The Apache HTTP Server Loaded: loaded (/usr/lib/systemd/system/httpd.service; enabled) Active: active (running) since Thu 2014-09-18 10:36:53 CEST; 4s ago Process: 6812 ExecStop=/bin/kill -WINCH ${MAINPID} (code=exited, status=0/SUCCESS) Process: 6808 ExecReload=/usr/sbin/httpd $OPTIONS -k graceful (code=exited, status=0/SUCCESS) Main PID: 6843 (httpd) Status: "Processing requests..."

mod_gnutls is provided by EPEL, not CentOS. I suggest using the support venues provided by EPEL. | |
As I posted in section "Additional Information" you can find here the whole story: https://bugzilla.redhat.com/show_bug.cgi?id=1143908 --------%<--------%<--------%<--------%<--------%<--------%<--------%<--------%< (In reply to Nikos Mavrogiannopoulos from comment #9) > I don't think that mod_php is in epel7, so you'd have to open this bug to > rhel7, or to centos7. O.K. I've done, how you told me: https://bugs.centos.org/view.php?id=7669 --------%<--------%<--------%<--------%<--------%<--------%<--------%<--------%< O.K. I've done my job and opened a bugreport here at centos7. You told me I should go to the EPEL guys. I'm just feeling like Bill Murray in the movie "Groundhog Day" - or in other words: Am I in an endless timeloop? I think so! |
|
I've just retried your steps, and they happen here as well. I'Ve also went through the bugzilla entry from EPEL re. that issue. IMHO the best course of action would be to resubmit your bugreport against RHEL7, and see what comes from that. Once it gets fixed upstream, CentOS will inherit the fix. My initial reply has been the way it is because 3rd party packages are not supported in this buzgilla (meaning mod_gnutls). Not shure how this will be handled upstream, might be interesting. |

Thank you for support - as you told me, I opened a new bug-report against RHEL7: https://bugzilla.redhat.com/show_bug.cgi?id=1149991 |
