Description

If qdroutered is started with --daemon and --user options, and then is killed with SIGABRT or crashes, it does not produce a core file. Note both --daemon and --user are reqiured to produce the problem, either alone does not. Tested on RHEL6 and Fedora 21 as follows:

Send core files in /tmp, since --daemon will set current directory to /

# echo /tmp/core.%e.%p > /proc/sys/kernel/core_pattern

Verify we do get a core file with just --daemon

# qdrouterd --daemon
# pkill -e -6 qdrouterd
qdrouterd killed (pid 11482)
# ls /tmp/core*
/tmp/core.qdrouterd.11482

Now add --user

# rm /tmp/core*
# qdrouterd --daemon --user aconway
# pkill -e -6 qdrouterd
qdrouterd killed (pid 11432)
# ls /tmp/core*
ls: cannot access /tmp/core*: No such file or directory
