I had this error often on a underprovisioned Virtual Machine… once I added more memory it seemed to clear up. just a thought.

@sgvfr it is a VM… running over xenserver… but i already set 12GB of ram… so i think i can exclude that…

Hi,

possibly increasing debug level brings some light in?

I am not perfectly sure but it might be a http status code. Just as an additional idea.

@Christian_Voelker id0n’t know if is related and if you can help… but sometimes when i update/install packages in the server i get the hba.conf error… like

Traceback (most recent call last):
  File "/usr/sbin/univention-pkgdb-scan", line 36, in ?
    univention.pkgdb.main(sys.argv[1:])
  File "/usr/lib/python2.4/site-packages/univention/pkgdb.py", line 935, in main
    pkgdbhdl = pgdb.connect(pkgdb_connect_string)

    dbtty, dbuser, dbpasswd)
pg.InternalError: FATAL:  no pg_hba.conf entry for host

Does this help?

@Christian_Voelker no, i already try that… in the slave server i get error that the file don’t exist

If run the same command, in the master it says the host already added
