The ‘Disk Quota Exceeded’ error is when your run out of storage.
I know InfinityFree says ‘unlimited storage’, but they use Linux - and Linux has a storage system called ‘inodes’
The limit for inodes is 30019
Every inode is 1 file. (so how many files do you have in the dynmap folder?)
InfinityFree can’t do anything about Linux… the inodes limit is hardcoded.
The limits for people are set by the host. Because this is a free host, you don’t get many inodes. On premium, you get many more, and on premium business plans, you get unlimited inodes with fair usage terms.
Hosting 600K mini images doesn’t seem like fair use to me, in my opinion.
Because they spend money on premium services and VPSs.
