I recently ran out of space on the parition hosting my zabbix database. I stopped the zabbix_server daemon, stopped the mariadb daemon, cleaned up the filesystem, then restarted everything. I noticed that I wasn't collecting new data after the restart, and upon looking at the log, I see that I have the follow error repeated 50 times:

"zabbix_server [8518]: ERROR file:dbconfig.c,line:2115 Something impossible has just happened."

I googled the error and saw zabbix issues related to items with incorrect status, and entries in other tables, but each time I ran the test query, no records were reported. It seems that the line with the error (2115 in my case) determines what table to check. I looked at the dbconfig.c file on github and it's only 103 lines, so I was hoping someone here could help.

Note, after restarting zabbix_server and mariadb again, I'm now collecting data, but the error still shows up every time I start zabbix_server.

Thanks!
