Re: [orion-dev] Problems with self hosting on orion.eclipse.org

I can confirm from the logs that this was an "out of handles" problem. There were some other error patterns in the log related to files that I hadn't seen before, so I have opened some bugs to follow up on those. I am also closely monitoring the handles now to help find patterns. For anyone who wants to check today, I am logging current open handle count every couple of minutes here:

http://orion.eclipse.org/file/Bw/handles.20120126.txt

Column 2 is the total handle count, and column 3 is the handles opened by Lucene (within the same server process). When column 2 hits 1024 the server falls over. I could try some strategies like auto-restarting the server when handles run out to workaround this to avoid disrupting people. Unless we have a new bug I believe it is Lucene leaking these handles, but I need to gather more recent data to confirm this. I am going to start the process of CQ's for a newer Lucene version. For anyone who wants to follow further investigation you can find updates on this bug:

Was out at a Play, just got back. I saw the same thing and restarted the server.

John and I have been seeing increasing 'handle' problems with the Orion process. So this will have to be a focus area for testing to see if we can find out what in particular is causing the problem.

Perhaps it's the increasing load cause by all these people wanting to contribute. Success has it's drawbacks ;-) ha

Will monitor it and see if we can update everyone on the call tomorrow.

Hi,

Can't seem to access my self hosted environment - seems to timeout:


HTTP ERROR: 500

Problem accessing /. Reason:

    Could not read file: /home/admin/current/eclipse/serverworkspace/D/D/CT/bundles/org.eclipse.orion.client.core/web/index.html.


Powered by Jetty://

Tried on Chrome and FF, cleared localStorage, cache, restarted browsers.

Anyone else see this? Any advice?


Anton
