Subject [jira] Commented: (COUCHDB-963) Erlang processes crash when running the delayed_commits test on Windows Server 2008
Date Wed, 02 Mar 2011 01:22:37 GMT


Adam Kocoloski commented on COUCHDB-963:

Summarizing our IRC conversation, I'm +1 on setting the autorestart bit on the daemonized
version.  Also +1 on submitting a bug report to OTP regarding init:restart() and erl.exe/erlsrv.exe

>                 URL:
>             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, dch_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.
