Adam,

I'm looking into this.

I'm not sure why you are getting the problem repeated when you do Administration - Find user - edit. You could try clearing the user cache - in SysAdmin go to "Cache Management" and click on the "Remove" link. This will attempt to clear any user details out of the cache.

If people are logged in, then their details will be recached again pretty quickly, but its worth a try.

I can't reproduce the problem, but we have heard of other users having this problem. But because I can't reproduce it, we might just have to try a few things to see if we can track down the problem.

Could you check your transaction isolation setting for MySQL? Can you try to find your mysql.ini file (under Windows) or my.conf (on Unix/Linux/Mac).

The mysql.ini (Windows) is usually in either your MySQL Server directory (e.g. C:\Program Files\MySQL Server 5.0) or in your Windows directory (e.g. C:\Windows).

The my.cnf (*nix/Mac) is usually in \etc.

Find the entry "transaction-isolation". It should be set to READ-COMMITTED:

transaction-isolation=READ-COMMITTED

What is it set to?

We have the cache (which is what is throwing the exception) set to match READ-COMMITTED.

I'm also looking into whether we can use a newer version of the caching software, as that has some different options.

Adam,

Note that after changing the transaction-isolation in the mysql.ini, you will need to restart mysql to take effect. So first stop LAMS, then MySQL. Start MySQL and then LAMS again and that should do.

I have checked the MySQL configuration.
We have 5.0.38 version and there is no
transaction-isolation entry at all in my.conf file
do you suggest to add it ?

Yes.

Have a look at this page in the wiki regarding MySQL configuration for LAMS.

Thanks,
