I'm using simple webhosting with php5+APC support. My hosting supported all forum requirements.

Very interesting...if wait sometimes like 5-10-15 minutes forum works again!

What is the problem, how do u think?​

Unable to allocate memory for pool.

Related to APC. Here is some info:

You should also have an apc.php file somewhere that you can view to check the status of your APC cache. That will indicate if there are problems or not.
