I have nowhere else to ask, I just noticed that my server isn't responding, or it takes a lot of time. I have a classifieds website which uses mysql and php.
I use PUTTY and wrote
top to see whats bothering the server. There is something EATING up CPU, and it is some java application. No idea what it is. Anybody know what I should do? Please guide me?
Have I been hacked?
EDIT: I just restarted the server from a control-panel my VPS provider offers, now the numbers are ok... What could it been?
I use SOLR, and that is the only Java because it uses Jetty as a container.
Could this be that a call was made and not cancelled and hence it caused a loop somehow. Anybody who used solr experienced this?
