Hi, I have a web server running Testing with apache 2.4.37 and php 7.3. The purpose of the server is to run owncloud. However, after the nightly restart the server stops working. The logs show the following:
/var/log/apache2/error.log.1 [Fri Nov 23 00:00:01.526101 2018] [mpm_prefork:notice] [pid 2858] AH00171: Graceful restart requested, doing restart /var/log/apache2/error.log [Fri Nov 23 00:00:01.622137 2018] [mpm_prefork:notice] [pid 2858] AH00163: Apache/2.4.37 (Debian) OpenSSL/1.1.1 configured -- resuming normal operations [Fri Nov 23 00:00:01.622156 2018] [core:notice] [pid 2858] AH00094: Command line: '/usr/sbin/apache2' [Fri Nov 23 00:00:01.626193 2018] [core:notice] [pid 2858] AH00052: child pid 5383 exit signal Segmentation fault (11) [Fri Nov 23 00:00:01.626217 2018] [core:notice] [pid 2858] AH00052: child pid 5384 exit signal Segmentation fault (11) [Fri Nov 23 00:00:01.626222 2018] [core:notice] [pid 2858] AH00052: child pid 5385 exit signal Segmentation fault (11) [Fri Nov 23 00:00:01.626227 2018] [core:notice] [pid 2858] AH00052: child pid 5386 exit signal Segmentation fault (11) These segmentation faults keep going so that the error.log file grows to hundreds of MB within a few hours. When I do "service apache2 restart" the server works properly again until the next nightly restart. Any idea what could cause this problem? Package versions: libapache2-mod-php7.3/testing,now 7.3.0~rc4-1 amd64 php-apcu/testing,now 5.1.12+4.0.11-2 amd64 php-redis/testing,now 4.2.0~rc2-1 amd64 php7.3-opcache/testing,now 7.3.0~rc4-1 amd64 certbot/testing,now 0.28.0-1 all First I had the opcache enabled in /etc/php/7.3/apache2/php.ini, but then I disabled it since many people reported issues with opcache causing segfaults. However, the problem still persists. I also tried to switch the memcache setting of owncloud from APCu to Redis, but also no effect. Owncloud's cron.php is executed via www-data's crontab. I also ran "certbot renew", but it does nothing because the server's certificate is still valid and thus the server keeps running. Best regards, Dino
