Please check old processes on fl-hn1 as low on memory #248

Closed tatarsky closed 6 years ago

tatarsky commented 6 years ago

The fl-hn1 headnode is reporting low memory. Looks mostly like over the past 228 days its been up there is a fair collection of disconnected or forgotten items. No one item is a large consumer.

If you do:

ps aux|grep yourusername

You might see processes that you forgot about or don't know are running. I don't tend to clean items like this in case you are using them but I can see many items probably forgotten.

You can simply kill them with kill (process id) which is the second column of that ps command above. Some may require kill -9 (process id)

If you need help doing this just provide me or @hirokomatsui permission to kill off items with your username older than some date. Remind me your username if it doesn't match your Git ID.
