Did you check if the tables are corrupt?

from command line, do (it is always safe to do it):

mysqlcheck -v --databases <your eprints database>

or just

mysqlcheck -v -A

if you've only eprints in the mysql instance.

Let it run for a while until it finishes.

i checked the mysql and here is the result..

mysql> use edocs;

You can turn off this feature to get a quicker startup with -A

Hi Zen,

Looking at the logs (snippet below), it appears as though you have a user record, whose "preference" field, which is stored as a serialized data structure cannot be "thawed" (i.e. converted back into a data structure and loaded as a variable).

The issue seems to relate to this field being too large (more than 2^32, approx. 4 billion bytes).  I am not sure how this field could have got anywhere near this large, as the "preference" field is usually a few hundred characters/bytes at most.  I suspect this issue also explains the "[error in script]" error messages you are getting on the back on some abstract pages for the "Depositing User".  If you know which user deposited these eprint records then that will be the one causing the issue.  There of course may be more than one user with this issue (although I can see you only have a couple of dozen users in total).  If you could login to MySQL and run the following query on the user table, this may help identify the user or users causing this problem.

SELECT userid, LENGTH(preference) AS pref_size FROM user ORDER BY pref_size;

Hi Zen,

The internal server error page is not very useful at debugging the problem.  You will need to look in your webserver error logs.  On Red Hat Linux based systems this is usually /var/log/httpd/error_log or /var/log/httpd/ssl_error_log.  On Debian/Ubuntu based Linux this will likely be /var/log/apache2/error.log.  I would recommend loading one of these pages showing an internal server errors whilst tailing the error log file, e.g.

tail -f /var/log/apache2/error.log

and see what error messages you get.  If you do not see an error message, check if there are any other error log files you can tail, as Apache configuration can modify where errors are logged.

Once you have the error message from tailing the logs, post it back to this list and I will see if I can further advise.  One quick thing I might try first is ensuring the database schema for your EPrints is up to date by running:

EPRINTS_PATH/bin/epadmin update ARCHIVE_ID
