I am using the Ubuntu image, we created a hosted VM based on the appliance with what I think are the same specs the VM had, dual core CPU, 4Gb of RAM. It has been working great but I get the feeling I have abused it and performance has taken a nosedive. I have been testing the parsing of logs, I have filebeat feeding logs from a folder on my laptop, my process has been to create extractors, feed in some logs (typically up to 6 10mb log files), review the data then delete the index and repeat, adding extractors etc. as I go. I am up to index graylog\_16 so it’s fair to say I have been through that many iterations, now however the server is slammed, NMON shows one java process using 198% CPU. I have tried restarting graylog (graylog-ctl restart) and rebooting the server but it makes no difference. I am not concerned about performance overall right now but I would like to know if there’s a way to “reset” things, I’m no expert but I’m guessing it is the journal that is overwhelmed? Without rebuilding the server is there a way to reset everything back, ideally without losing my configuration setup? Thank, Chris. ---

After it running with the CPU maxed out for a day I decided to give **graylog-ctl cleanse** a shot, even after that and a reconfigure the processors are still pegged. I had hoped that would at least reset things even if I had to reconfigure everything again. Any other suggestions? ---
