You'll find more informations in bugreport "Bug 1143908 - mod_gnutls crashes httpd if mod_php is loaded (CentOS 7)" here: https://bugzilla.redhat.com/show_bug.cgi?id=1143908 Thanks for the report. If this is an issue for you on productions systems, please raise a ticket through your regular Red Hat support channels to make certain it receives the proper attention and prioritization to assure a timely resolution. http://www.redhat.com/en/services/support It's a evaluationsystem, based on CentOS7 - I've no customer-id on http://www.redhat.com/en/services/support so I must hope someone will fix this bug in the php-packages on RHEL7. Seems very probably related to https://bugs.php.net/63595 As I can say, yes it is. Nikos Mavrogiannopoulos said so: https://bugzilla.redhat.com/show_bug.cgi?id=1143908#c8 *** Bug 1152162 has been marked as a duplicate of this bug. *** Notice, as libcurl doesnt use gnutls (but only nss), php-curl is not affected by this issue. So only (kwown as) affected : mod_gnutls and freetds (php-odbc or php-mssql) Possible mitigation: build gmp as shared, as in php 5.5+, so it can be disabled (not a very common extension) A heavy patch have been attached to upstream bug report, waiting for php internals feedback. php-mapi (zarafa in EPEL) is also affected, see #1075617 Should be fixed with: https://rhn.redhat.com/errata/RHSA-2015-1135.html *** Bug 1143908 has been marked as a duplicate of this bug. *** |
Description of problem: 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) How reproducible: I have mad many tests last day with different CentOS 7 hosts. 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..."
