Slow log out.

[wjwieland]

Steps to reproduce

1. Log into nextcloud
2. Log out

Expected behaviour

Log out should be as fast as log in. There should not be a delay to get out of the system.

Actual behaviour

I have two instances of Nextcloud (one mine, one is a friends). Both are V 13.1. Either may take anywhere from 5 to 30 seconds to achieve log out.

Without access to your command line download the data/owncloud.db to your local

SELECT * FROM oc_appconfig WHERE appid = 'user_ldap';

Eventually replace sensitive data as the name/IP-address of your LDAP server or groups.

I'm also observing this in NextCloud 13.0.7. Any hints what might be causing this?

[wjwieland]

@gohrner
Oddly enough, after I 'click' on logour the second time, it immediately logs out and goes back to the login page. If I don't click the second time, it will grind away for up to ~30 seconds before finally logging out....odd....and bothersome.

I have a similar problem on nextcloud 14.0.3, and actually a even worse issue.
When is trying to logout all the sessions under the same domain are closed even the sessions under shibboleth. Is this related on having authentication with ldap?

[wjwieland]

I upgraded to NextCloud 14.03, same issue. Will check into the log-rotate setting above mentioned by @nextcloud-bot. The second click behavior mentioned still persists as well. Same applies to Nextcloud 14.04. This is after following steps in https://docs.nextcloud.com/server/14/admin_manual/issues/general_troubleshooting.html#service-discovery.

[linuxkafe]

In 14.04 this issue was solved to me :)

For me the logout takes 15s (owncloud takes < 1s).

),
'memcache.locking' => '\\OC\\Memcache\\Redis',

Logout takes really long some times (latest stable 15.x). In chromium, if I do 'empty cache and hard reload', logouts becomes fast again.

[agarek]

Same issue and no solution found :-(

Apache 2.4.29
PHP 7.2.15

[deddc23efb]

Same issue in 15. I saw it in 14 too. Clicking the logout again after a few seconds wakes it up for me.
