Dave Cottlehuber commented on COUCHDB-963:
------------------------------------------

Also replicated, EC2 large instance, w2008 r1sp2 datacenter ed. 

My reading is that this is an erlang vm problem.

Not all restarts fail:
[Tue, 08 Feb 2011 08:16:25 GMT] [info] [<0.362.0>] 125.236.236.206 - - 'POST' /_restart 200

[Tue, 08 Feb 2011 08:16:27 GMT] [info] [<0.398.0>] Apache CouchDB has started on http://0.0.0.0:5984/

but others do - 7 minute delay is my manual restart coming in:

[Tue, 08 Feb 2011 08:23:37 GMT] [debug] [<0.2056.0>] 'POST' /_restart {1,1}

          {'Accept-Language',"en-us,en;q=0.5"},
          {'Cache-Control',"no-cache"},

[Tue, 08 Feb 2011 08:23:37 GMT] [debug] [<0.2056.0>] OAuth Params: []

[Tue, 08 Feb 2011 08:23:37 GMT] [info] [<0.2056.0>] 125.236.236.206 - - 'POST' /_restart 200

[Tue, 08 Feb 2011 08:30:30 GMT] [info] [<0.34.0>] Apache CouchDB has started on http://0.0.0.0:5984/

So it looks as if couchdb shuts down cleanly through;:

handle_restart_req(#httpd{method='POST'}=Req) ->
    couch_httpd:validate_ctype(Req, "application/json"),
    ok = couch_httpd:verify_is_server_admin(Req),
    couch_server_sup:restart_core_server(),

which is short & sweet:
restart_core_server() ->
    init:restart().

leaving couch now & into (I think) the vm:

restart() -> init ! {stop,restart}, ok.

>                 URL: https://issues.apache.org/jira/browse/COUCHDB-963
>             Project: CouchDB
>          Issue Type: Bug
>          Components: Infrastructure
>    Affects Versions: 1.0.1
>         Environment: This Windows box is a virtual machine
> Windows Server 2008 Standard without Hyper-V Service Pack 2 64-bit
> 2 GB RAM
> 2 Core Intel Xeon CPU @ 2.53GHz each
>            Reporter: Terry Smith
>         Attachments: Apache CouchDB.debug.2, couch.log
>
>
> The debugging I've done points to this being an erlsrv.exe bug. Here my steps to recreate.
> Install 1.0.1 CouchDB as a service using the Windows Binary Installer. I did not select to "Start service after installation".
> Edit the local.ini to set the logging level to "debug".
> Go to the service control panel and start the Apache CouchDB service.
> Go to Test Suite in Futon and run the "delayed_commits" test.
> After about 15 - 20 seconds go to the service control panel and refresh to see that the service is no longer running. ProcessExplorer verifies the erlsrv.exe and erl.exe processes are not running. The last message in the log is a _restart command that returns 200. 
> When I run CouchDB using CouchDB.bat. The test completes without crashing.
> When I set the DebugType in the registry HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Ericsson\Erlang\ErlSrv\1.1\Apache CouchDB to 1 (DEBUG_TYPE_NEW) to get a erlsrv.exe log, the test completes without crashing.
> I will attach the log files from CouchDB and erlsrv.exe.
