This seems to be a consequence of the Bug 453049 :
https://bugs.launchpad.net/ubuntu/+source/couchdb/+bug/453049

See the fix at my comment :

that resolves this stop bug.

I have the bug... trying to install couchdb 0.10.0

After install, I cannot stop, it continually restarts itself, and starts to fill up /var/log/couchdb/couchdb.log with errors of

[Fri, 06 Nov 2009 15:58:41 GMT] [error] [<0.66.0>] {error_report,<0.24.0>,
              {<0.66.0>,crash_report,
               [[{initial_call,{mochiweb_socket_server,init,['Argument__1']}},
                 {pid,<0.66.0>},
                 {registered_name,[]},
                 {error_info,{exit,eaddrinuse,
                                   [{gen_server,init_it,6},
                                    {proc_lib,init_p_do_apply,3}]}},
                 {ancestors,[couch_secondary_services,couch_server_sup,
                             <0.1.0>]},
                 {messages,[]},
                 {links,[<0.53.0>]},
                 {dictionary,[]},
                 {trap_exit,true},

                 {heap_size,987},
                 {stack_size,24},
                 {reductions,446}],
                []]}}

My understanding is that this is a bug when its trying to restart itself - and already sees that it's running. So now it does stop, but caught in a loop trying to restart.

This could be a big deal, but not sure if its just my setup or not.

Not even uninstalling keeps couch from running too... its like there's no way to get rid of it without a reboot.

I apt-get remove --purged, and apt-get remove / reinstalled, same issue

[cjazz108 (adamjpetty)]

Just reinstalled on my laptop - that had no previous couch install (except ubuntuone).

The same bug occured... could not stop.

The script reports (couchdb stop.... [ok]) but I can still update documents in futon (the web admin for couch).

Also trying to restart gives same errors above, and log file continues to be filled (even after --purge).

Only way to stop couch - is to reboot.

If left for a while - I could see this taking down a few computers, especially if they don't have a seperate partition for /var.

You can kill couchdb without rebooting by using:

ps -U couchdb -o pid= | xargs kill -9

Problem still exists on Ubuntu 10.4 Server

[Mathias Gug (mathiaz)]

couchdb will not be killed by its init script because signal 1 is ignored if the daemon has been started during package installation:

$ cat /proc/$(cat /var/run/couchdb/couchdb.pid)/status
[...]
SigIgn: 0000000000001007
[...]

If couchdb has been started by its init script during boot time or from the console then signal 1 is not ignored:

$ cat /proc/$(cat /var/run/couchdb/couchdb.pid)/status
SigIgn: 0000000000001006

The couchdb script uses signal 1 to kill the erlang vm.

[Mathias Gug (mathiaz)]

Some conversations with cjwatson on IRC lead to two potential fixes to address the issue:

1. < cjwatson> mathiaz: I meant calling sigaction in the daemon itself

2. < cjwatson> or create a tiny C wrapper that does struct sigaction sa;
                  memset (&sa, 0, sizeof sa); sa.sa_handler = SIG_DFL;
                  sigemptyset (&sa.sa_mask); sa.sa_flags = 0; sigaction
                  (SIGHUP, &sa, NULL); and then execs the program

It seems that option 1. may not be possible if erlang doesn't support signals.

Debian fixed this in 1.1.0-2. This version likely will not make it in to Precise as-is; someone needs to go through SRU procedure. I am closing the bugtasks for old versions of Ubuntu and adding ones for new versions
