I have installed latest version of SEF, almost every thing work properly but only for a short time, I mean after 30 to 50 user visits the website, web site crashed and no page open even home page until SEF database purged.
It is surprising for me that no error found in site error_log while site crashed. after database purged site and all pages working properly with SEF URL. If SEF uninstalled then site working properly for ever( I have test this for one month).
I am very disturbed due to this situation my users face a lot of problem and day by day number of users decreased.
Please help me accordingly.

Thanks

To be able to help you, first of all it is needed to determine what is the problem.

Please, specify what you mean by \"the site has crashed\". What happened? Did you gen an error message? Did you get a \"blank page\"? Something else happened?

If you got an error message, please post it here. You you got just a blank page, you will need to turn error outputs on at your site temporarily to see what is really the problem. Do that and again come back with the error message. Also please state what version of JoomSEF you are using.

You might also check this topic, if it is not also your case: www.artio.net/en/fireboard/joomla-extens...oo-many-pages/view-2.

I have this same issue, with joomsef 3, and I still have yet to figure it out. The Too Many Pages thread was not helpful in my case. Also if I restart apache the site will work for while longer then crash.
