Owncloud 8 crashes Apache on brand new fresh install Ubuntu 14.04 [Workaround] #14188

Closed BoBeR182 closed 9 years ago

BoBeR182 commented 9 years ago

Hey everyone,

I was experiencing the same issue on a new installation, and after some digging around I have successfully concluded that the issue was the cache that was being used.

FYI im on ubuntu 14.04 server.

after running apt-cache depends owncloud i get the following list

Depends: owncloud-server Depends: owncloud-config-apache Depends: owncloud-3rdparty Depends: owncloud-app-activity Depends: owncloud-app-files Depends: owncloud-app-files-encryption Depends: owncloud-app-files-pdfviewer Depends: owncloud-app-files-trashbin Depends: owncloud-app-firstrunwizard Depends: owncloud-app-templateeditor Depends: owncloud-app-user-ldap Depends: owncloud-app-external Depends: owncloud-app-files-external Depends: owncloud-app-files-sharing Depends: owncloud-app-files-versions Depends: owncloud-app-gallery Depends: owncloud-app-updater Depends: owncloud-app-user-webdavauth Depends: owncloud-app-files-locking Depends: owncloud-app-files-texteditor Depends: owncloud-app-files-videoviewer Depends: owncloud-app-provisioning-api Depends: owncloud-app-user-external |Suggests: clamav Suggests: clamav-daemon Suggests: smbclient Suggests: libreoffice-writer Recommends: mysql-server Recommends: curl curl:i386 |Recommends: exim4 Recommends: citadel-mta courier-mta esmtp-run exim4-daemon-light lsb-invalid-mta masqmail msmtp-mta nullmailer opensmtpd qmail-run sendmail-bin ssmtp xmail dma:i386 dma exim4-daemon-heavy postfix |Recommends: php5-apcu Recommends: Conflicts: Conflicts: owncloud-fhs:i386

As you can see that php5-apc conflicts with the owncloud fhs so php5-apcu is installed instead. This was confirmed by running apt-cache policy on both php5-apc and php5-apcu.

Seeing as that is a recommended package I proceeded to purge it from the system. Owncloud functionality was not effected at all. My OC has been up for over 12 hours now.

Wanted to share this with you all as I hope it will help alot of you as it helped me.

Aha. I've noticed OC8 was giving Apache trouble and was looking on here for answers. My task was complicated by having migrated from SQLite to MySQL at the same time as I upgraded, so wasn't sure if that was part of the problem, but removing php5-apcu seems to have done the trick here, too.

You cannot use 2 caching modules at the same time. Select between apcu it is newer.

@jnweiger please have a look - THX

simonnzg commented 9 years ago

It depends if php5-apc is Requires anywhere else on the particular computer installation. Best to remove the conflicting Recommended. Not ideal, but avoids too much hell.

jnweiger commented 9 years ago

On Ubuntu-14.04, the situation with apc is tricky. When I ask for apc, I automatically get apcu. This is what happens to me:

# apt-get install php-apc
Reading package lists... Done
Building dependency tree       
Reading state information... Done
The following extra packages will be installed:
  lsof php5-apcu php5-common php5-json psmisc
Suggested packages:
  php5-gd php5-user-cache
The following NEW packages will be installed:
  lsof php-apc php5-apcu php5-common php5-json psmisc

@BoBeR182 I don't follow your description with the conflicts. The package owncloud-fhs is not installed at all. It has no influence on the dependency resolution. Also, it does not conflict with any apc or apcu packages.

I'll fix one error in the Recomends: line. It asks for either php5-apcu or php5-apc -- A package 'php5-apc' does not exist in debian universe. It should say php-apc, without a '5'.

I'll also make it a Suggests: instead. Unless we have a strong reason to advocate for a caching system, I see this negative experience as a valid reason to not Recommend any.

Now, this is a workaround:

1. Create a bash script

#!/bin/bash
sudo -i & 
sudo apache2 restart

2. Setup a cronjob crontab -e

3. Make the script run every 3 hour (that's about when the server crashes)

00 */3 * * * your_script.sh

4. Delete the crontab when this issue is fixed(!)

I made a very similar script, but it simply hupped apache every couple of hours. On 14 Feb 2015 00:04, "Daniel Hansson" notifications@github.com wrote:
