[Pkg-bareos-devel] Bug#884011: bareos-filedaemon: bareos-fd crashes - fills /var/lib/bareos/ with core files

Mon Oct 29 07:55:53 GMT 2018

Package: bareos-filedaemon
Version: 16.2.6-4
Followup-For: Bug #884011

Dear Maintainer,

today systemd reported "bareos-filedaemon.service" as failed. Some other
"bareos-fd" was running and blocking TCP port 9102, so systemd "failed" to
start the new "bareos-fd":

# lsof -i :9102
COMMAND    PID USER   FD   TYPE DEVICE SIZE/OFF NODE NAME
bareos-fd 1701 root    3u  IPv4  12762      0t0  TCP *:bacula-fd (LISTEN)

Actually systemd starts "bareos-fd" successfully in a loop, but it
crahes / aborts, systemd writes a core file and restarts it again -
filling up my disk again:

# journalctl -u bareos-filedaemon.service

Maybe some bad interaction between the old SysV-init-script and systemd?

1. Bareos-FD should not "crash" with SIGSEGV when the TCP port is
   already taken, as that triggers a Core-dump.
2. systemd should not restart the crashed bareos-fd every 30s if it
   crashes each time (with the same error).

Thanks.
Philipp
