Original GitHub issue: https://github.com/modoboa/modoboa/issues/899

Dear Devs,

I got a 100% CPU usage of uwgi on modoboa logout (as soon as I click on the logout link uwsgi gets to 100%): 4729 modoboa 20 0 301960 89708 14144 R 99,7 2,2 0:08.70 uwsgi

Any idea where it could come from ?

I am using the modoboa version: 1.5.3 and ldap authentication backend.

Romain

I forgot to tell that the 100% uwsgi process never ends...

Looks like there is an infinite loop somewhere... Have you tried using a local account ? (ie non LDAP)

I just tested it and it works fine with non-ldap users (admin and a test user).

I have the same problem. Not using LDAP.

SimpleUsers results in 100% cpu usage by a uwsgi process and they never get logged out.
Also DomainAdmins.

SuperAdmins can log in / out just fine without any cpu spikes.

Modoboa version 1.5.3.

The issue reported by @ogg1980 was due to a wrong filesystem configuration. (emails were not stored into the location used by dovecot)
@romainreuillon Could you try to logout with such a user and check mail logs to see if there is anything interesting inside?

@romainreuillon I close the issue for now (required by bountysource). Do not hesitate to reopen it when you'll do your tests.
