SQLSTATE[42000]: Syntax error or access violation: 1461 Can't create more than max_prepared_stmt_count statements (current value: 16382)

I got this error, I couldn't figure out what is raising this issue. Previously, I ran a CRON job to run jobs every minutes in shared hosting server, I got suspicious that it caused the issue, so I deleted the CRON job and told the server support to clear all the process that were generated. It fixed the issue, no after 7 days the issue occurred again this time I haven't even created CRON job. Please any one who can help me figure out this issue and solve it?
