Hi,

My forums were working right and then, entering a forum thread today it happened.

I got the "A critical error has occurred" exception...

Thanks for your response, Crispy!!

That will solve the cause, that, I think has to see with a slow page creation and that it tries to access some information it doesn't has on memory... Also something about the worker process which recycles the configuration of the forum from the cache... isn't it right?

Why don't we use the lazy load pattern and, identifying when the config has been unloaded, loads it again? and doing so for the solpart should be great too... well I'm not into the core or anything like that, but only try to suggests ways... helping whenever I feel I can help... only a humble opinion...

Apart from this, if the page doesn't load, I don't have access to the forum and the only way I see is to re-do it again... that makes me want to do a copy of any "complicated" module on my website... mmmm... not quite practical...

Any ideas or opinions??
Yeah, to back-up everything... but in a community that would mean loosing a day or half a day of messages in the forum...

Any guidance will help, Thanks!!!
Jose

Thanks!

that was fast! amazing! :)

what I am asking is that if the forums "hang" I can't access the configuration and take this solpart flag out. how do I do that? the only thing I can think is to locate the config in the database and changing it manually, is it right?
