I have increased the limit from 256M to 512M.
@Gianluca, which limit have you specified when applying the solution?
There is a possibility that specified limit was not enough.
I had this issue trying to delete a subscription, i followed this guide but it seems the restart of the Plesk management service does not "read" the new php.ini, in fact after the modification i tried again to delete the subscritpion but the error was the same.
Then i tried to restart Plesk services by "Plesk service monitor": i restarted the entire "Plesk run-time" and "Mail service" then tried to delete the subscription again, no luck.
Finally i restarted the server and finally i was able to delete the subscription.
@Gianluca, thank you for the provided info.
If the issue will reoccur, increase the limit further. In case it would not help, consider submitting a ticket to Plesk Technical Support.
