Level 10 Debug Log

On some of my 4.2.2 and 4.1.17 servers, the logs are getting filled with the following error:

[2015/06/24 03:46:17.051077,  1, pid=32134, effective(0, 0), real(0, 0)] ../source3/librpc/crypto/gse.c:466(gse_get_server_auth_token)
  gss_accept_sec_context failed with [ Miscellaneous failure (see text): Failed to find cifs/storage-03.mr.lfmg.de@MUC.MEDIZINISCHE-GENETIK.DE(kvno 1) in keytab MEMORY:cifs_srv_keytab (arcfour-hmac-md5)]

The messages are still logged, if I remove the machine account from (Samba) AD, delete all local Samba databases and rejoin the host to the domain.

Andreas Schneider supposed on IRC, because of the "no prev machine password" entry in the level 10 debug log, that the machine account password in secrets.tdb is missing/wrong. I run "net ads changetrustpw" which succeeded and I got a new password in the secrets.tdb in SECRETS/MACHINE_PASSWORD.PREV/MUC afterwards. However, this doesn't helped either and the above error is still logged.

Samba is self compiled and runs on CentOS 7.1.

I don't think this is a problem in current releases.
