Mobile TeraWURFL plugin - MAJOR memory leak / dll problem! 12 years, 1 month ago #7837

Info: Latest version of Mobile Joomla (1.0.1), Site is on 1.5.25 Joomla, running on IIS6 server. Have spent most of this morning tracking down a huge memory leak that was causing my server CPU to max out at 100% and make my site unavailable. Tracked it back to some kind of constant query that the Mobile-TeraWURFL plugin is doing. As soon as I disable the plugin (which doesn't seem to muck up the site on my mobile units) the CPU/Memory usage falls back to normal ranges. I assume it's ok to run without this plugin? Any ideas? Let me know if you need further info.
-- Thanks!

Yes, but in this case MJ cannot detect screen sizes to rescale images correctly.

What process had most of cpu load (php.exe, mysqld.exe, ...)?

I'm not in front of the server now, but I am pretty sure it was MySQL-NT.exe that was maxing out. In the SQL manager it seemed to be running a query on the jos_teraWURFL over and over. As soon as I would disable the plugin and restart SQL it clears up. By the way, this just seemed to crop up in the last RC - i updated to the final to see if it cleared up, but it does it as well. 

Any thoughts ?

Mobile-TeraWurfl plugin has option to use mysql4-compatible SQLs, maybe this way will reduce load.

By the way, this just seemed to crop up in the last RC

Mobile-TeraWURFL plugin was updated in July last time (MJ 1.0RC), and WURFL database was updated in November (MJ 1.0RC5).

Should I try to uninstall the plugin and reinstall the whole package? I did reinstall the package with teraWURFL disabled as I read of a similar situation in another forum post - I also switched from isam to innodb which I saw in another. Neither of these cleared up the problem.

So what is your suggestion? Is this an update or some change on my server?

What MySQL version do you use?
On my laptop I have Apache 2.2.17+PHP5.3.4+MySQL5.0.45, and this configuration works well. (Unlikely webserver and php matter here).
