Hello Nishit we will check and get back to you!
We could also flash all the errors manually by pushing flush button. It is good but it is not quite well as it is not working automatically with cron job. If it is hard for you to make errors flushing with cron can you please make a warning message to be displayed in red (Your error logs data is full, please use Flush Data button to clear.) message display every time when error logs table size reaches 500 MB.
We clear all the error logs and after 5 minutes reloaded the page and there were already tens of pages recorded again, did you check why this error logs comes and if we can fix it?
We need to make it flexible for the customer as it is manual flushing and site admin can be notified and clear it regularly as it over loads the sources.
