nc13.0.4 admin delete user failed

[stratege1401]

Was trying to verify if #8402 was reproductive with nextcloud upgraded to 13.0.4

Step1: As admin, manually created user02 + password
Step2: Log one time that user, edit a files and remove a folder --> some activities.
Step3: As admin, delete user.

Expected behavior:

• user02 should be deleted.

Actual behavior:

• user02 not deleted, a message appear on top middle of page with text "deleted test02 undo"
• user02 is gone, no more listed in page
• page refresh, user02 is back

redacted log without IP and username log:

GitMate.io thinks possibly related issues are #8098 (Adding new user fails), #7552 (Upgrade to 12.0.4 failed ), #5746 (Create user failed / password policy crash), #4017 (LDAP user not able to delete folder), and #1551 (Data of deleted user still there).

page refresh, user02 is back

Instead of refresh could you wait at least 30 seconds and then refresh. Is it still gone? Then it might be a missing event listener, because we wait AFAIK for 7-10 seconds (until the badge with the undo on top is hidden) until we trigger the actual delete. So it is basically a count down and only fires once 0 is reached. Usually there is a page unload event that we listen for and also trigger then.

UPDATED: please, consider this fix. I notice the Allowed memory size of 134217728 bytes exhausted but did not know it was a fatal error for php.

after modifying the /etc/php/7.0/apache2/php.ini to set memory_limit in concordance with my RAM and restarted apache2, i am now able to deseable/delete users without problems.
set from 128M to new value of 6144M as my system got 8192M
