[Pkg-net-snmp-devel] Bug#391203: snmptrapd likely makes the init script hang debconf

severity 391203 serious
thanks

Hi,

During a dist-upgrade...

[...]
Preparing to replace snmpd 5.1.2-6.2 (using .../snmpd_5.2.3-7_i386.deb) ...
Stopping network management services: snmpd snmptrapd.
Unpacking replacement snmpd ...
[...]
Setting up snmpd (5.2.3-7) ...
[...]
Installing new version of config file /etc/default/snmpd ...
Installing new version of config file /etc/snmp/snmptrapd.conf ...
Installing new version of config file /etc/init.d/snmpd ...
Starting network management services: snmpd snmptrapd.

[hangs here, after a while I press Ctrl+C]

dpkg: error processing snmpd (--configure):
 subprocess post-installation script killed by signal (Interrupt)

I then opened the snmpd.postinst and saw that it hangs after the exit 0.
Trying to avoid debconf hanging it, I added >&2 to the init script calls,
to no avail. Something inside the init script left file descriptors open.
Adding a db_stop after the init script stuff worked around the problem.

Notice that I have the trapd enabled, so it's probable that snmpd is okay,
but snmptrapd isn't, but fewer people noticed it because it's not enabled
by default.

Please fix this. TIA.
