If you think you can trust the following link, here's some information: https://malware.news/t/inside-one-xmrig-botnet-miner/17692 The xmrig software is an actual legitimate cryptomining program, but it is apparently being installed on vulnerable webservers by malware and generating profit for those who created the malware. If this is malware as I suspect, you're going to need to figure out what parts of your system are publicly accessible and vulnerable, patch them, and clean up the malware. Alternatively you could completely rebuild the server with newer software versions so it's completely clean and cannot be infected again. Thanks, Shawn

I am experiencing this too. For me the "solr" user is running "fs-manager" from with the directory "/var/tmp/.X1M-Unix. There is a "config.json", "out.log" and "xmrig.log" file present.

I don't think I see such process before. I have never heard of this, and have never seen it. Searching the source code, I cannot find that string. What OS is Solr running on? How did you start it? Exactly what are you looking at when you see this "fs-manager" process? Thanks, Shawn
./fs-manager process run under solr
Hi, I use Solr 5.5, I recently notice a process a process ./fs-manager is run under user solr that take quite high CPU usage. I don't think I see such process before. Is that a legitimate process from Solr? Thanks.
