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}

[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.

> Key: COUCHDB-963
> 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.
