[EP-tech] Re: Errors in apache logs

[mark.gregson at qut.edu.au (Mark Gregson)]

We see a lot of this also but with 3.2.7. I think that it's caused by EPrints trying to write when the connection has already closed, potentially because the user cancels an existing request or clicks on a second link before the first has loaded. I can produce a similar error this way:

EPrints::abort()\n, referer: http://blah.com
------------------------------------------------------------------
---------------- EPrints System Error ----------------------------
------------------------------------------------------------------
Error in send_page: :Apache2 IO write: (103) Software caused connection abort at /usr/local/eprints/perl_lib/EPrints/Page/Text.pm line 60

        eval {...} called at -e line 0

I don't know why you are seeing more of these now you're on 3.3.10.

Subject: [EP-tech] Errors in apache logs

Hi all,

after the migration to 3.3.10 we are noticing sometime some errors in the apache log like this one (~30-40 in a day):

------------------------------------------------------------------
---------------- EPrints System Error ----------------------------
------------------------------------------------------------------
Error in send_page: :Apache2 IO write: (53) Software caused connection abort at /opt/eprints3/perl_lib/EPrints/Page.pm line 78
------------------------------------------------------------------
  at /opt/eprints3/perl_lib/EPrints/Page.pm line 82
         EPrints::Page::send('EPrints::Page=HASH(0x2f28c5a0)') called at /opt/eprints3/perl_lib/EPrints/Apache/Template.pm line 153
EPrints::Apache::Template::handler('Apache2::RequestRec=SCALAR(0x2f4157e4)')
called at -e line 0
         eval {...} called at -e line 0

The system apparently is working like a charme and i'm not seeing errors when browsing the site.
How can i debug this type of errors ? The system doesn't report me which file (url) has be interested by this error, neither the archive (we have three different archive on the same server) ...

Best regards,
Paolo Tealdi
