[pkg-bacula-devel] Bug#783083: bacula-director-common: Bacula director has problems with kernel linux-image-3.16.0-0.bpo.4-amd64 (v3.16.7-ckt7-1~bpo70+1)

Hello Carsten,

    in the attachments you can find the results. But it seems to be
restarted correctly. I have tested it also with the brand new kernel and
the problem still persist. I cannot recognize any ps output differences
between the 3.x kernels (wrong functionality) and 2.x kernels (works well).

    But I have found another clue - there is a significant difference in
the director start log after the restart, I did not checked the debug
messages during the correct behavior with kernel 2.x. It seems the
director is not able to connect to pg database, so that's the reason why
the port 9101 is not opened. If you look on the two attachedn director
start logs, then in the case of the working 2.x kernel configuration the
DB is connected properly and some information is read from DB, in the
case of the problematic kernel 3.x the log of the debug messages ends
with the message about the first init:

 Generally I think, the postgres client has no problems with the
connections in the new kernel environment, so I gues, the problem must
be somwhere in bacula-director-pg package...
