Python is using almost 30% of SWAP file and it getting bigger and bigger. It could be ok but someone in my organization setup notification when SWAP file is larger then 40% and temporary I can't change it but I'm receiving all the time alerts from that server and it is annoying.

On that server is installed Bitbucket, PostgreSQL and Apache. I have tried swapoff -av && swapon -av but after a couple of hours it returned to previous size and again it's getting bigger and bigger.

Question is what for is use on that server Python process? I'm sure that Bitbucket or PostgreSQL is not using it but it looks that it some kind of network communication to external server (Bitbucket in our company is available also from external site) so it might be combined with Bitbucket.

What for is that process? Can I limit it somehow?

PS

Of course I could extend SWAP but for curiosity I need to know what for it is?

  • Python is a (scripting) programming language. Therefore the important thing to look for is not python itself, but what program python is running. Have you looked for it with ps -ef | grep python? Since swap space is associated with high memory usage you may want to look at top. See how to display top results by memory usage in real time – Philip Couling Jul 2 '20 at 9:34
  • Python is just an interpreter. The first step is to know what program this is. The fact that it happens to be written in Python is mostly irrelevant. lsof is not particularly useful information here. Start with ps ww 1459 – Gilles 'SO- stop being evil' Jul 2 '20 at 9:35
  • For ps ww 1459 output is: 1459 ? Ssl 35:08 /usr/bin/python /usr/bin/goferd --foreground – KUE Jul 2 '20 at 9:47
