OJS error logged by HelpTopicDAO.inc.php

[ramon]

Hello all,

Anyone experienced the following error logged:

Code: Select all

 [Fri Jun 29 00:39:54 2012] [error] [client 187.6.65.90] ojs2 has produced an error\n Message: WARNING: readdir() expects parameter 1 to be resource, boolean given\n In file: /usr/local/www/ojs2/lib/pkp/classes/help/HelpTopicDAO.inc.php\n At line: 130\n Stacktrace: \n Server info:\n OS: FreeBSD\n PHP Version: 5.3.13\n Apache Version: Apache/2.2.22 (FreeBSD) DAV/2 PHP/5.3.13 with Suhosin-Patch mod_ssl/2.2.22 OpenSSL/1.0.0h\n DB Driver: mysql\n DB server version: 5.5.25

I checked the file and it's using readdir according to PHP specs.
The user is claiming his OJS install is "going down" regularly, and this error gets logged.

Any ideas?

Hi Ramon,

I'd be interested in knowing what the $searchPath variable was containing, coming out of the foreach() loop that surrounds that readdir call. There is an opendir call that will return false if the $searchPath variable does not exist, so $dir would be false instead of a directory resource. That would probably cause the boolean warning you're seeing. If you could wrap that in a test to see what the path was, you'd be able to see if it existed on the server.

(I can't see how that would take down an OJS install though)

Regards,
Jason

Hello Jason,

I'm not sure if they have done it right..
This is what they have replied.
