I am having this problem

Zen 1.50 running 1.13.0

Files were trying to be generated so it just hangs.
So I tried making smaller file. It worked.
Called my Server company. Aparently they say the process took so much resources
that they shut down my cpu usage when it runs.
Someone suggested I optimize my database ( so I did)
When I ran the program again. It gave me an error
