what should I do? is there any way to prevent blocking?
you should change/upgrade your hosting package since it is not compatible with what required by Moodle: throttling DB queries per second is not a good choice for most of the Moodle core modules, neither any other limit on a time basis.
thanks matteo for reply but what do you mean of upgrade hosting packages?!
my server supports my moodle requests.
IF your server actually supports your Moodle requests, it should NEVER prevent you to upload SCORM packages too: if there's no throttling, how your server is able to detect you're creating some load in few seconds when publishing a SCORM package and then it stops you to access the server?
Please, contact your Provider and ask them to remove that constraint/protection e.g by means of upgrading your server or removing that check from your current server.
it don't prevent uploading my packages dear metteo
actually after uploading my IP blocks.
my server detects how much I access php files(college/theme/image.php). they call it logs. in fact if I access php files, it means I can edit every thing in my site, they blocks me because the server thinks I'm hacker :D
I talked to my provider. they say this is security option and con not be remove
