Why is this error showing up" This pool has exceeded its configured poolsize=0 bytes. A warning has been recorded for all members"?

My splunk stopped recording and I get this error, I've checked in licensing and I have the free 500mb license set up. Whats wrong?

You have indexed more than 500MB of data. When that happens Splunk will disable searching.
You'll need a new license, or a reset license.
