 Posted: Sat Jan 19, 2019 2:51 am Post subject: Dropbox gets killed by oom-killer |
 |
|
I have a woefully under-powered machine with about 236MB of RAM. It does what it's designed to do, so I don't plan to replace it, but lately, it keeps killing a memory hungry process; Dropbox, to be specific.

Is there anything I can do to run Dropbox without letting it get killed? I don't mind even if the whole system gets really slow.

1) I looked at the output of the OOM killer you posted. It really is Dropbox that consumes too much memory. For that reason, it wouldn't make sense to stop or tune any other processes.
2) It seems that swap isn't used much, so it won't help to increase swap space:
| Code: | Jan 16 13:43:57 gentoo kernel: Free swap = 4028272kB
Jan 16 13:43:57 gentoo kernel: Total swap = 4193852kB |
3) You may be able to reduce the amount of RAM requested by Dropbox. Do you know this article?
4) I understand that you don't want to replace your machine. But maybe you could add more RAM? |

The first thing I suspected (without looking at anything else) was the swap, so I increased to 4GB, but for whatever reasons, not much of it is used. Perhaps what could be swapped out was already swapped out.
I can't add more RAM, because it's soldered in.
My Dropbox has about 50K files, and Dropbox gets killed during the initial syncing. I'm going to just copy all files in Dropbox folder from another machine that already synced, and see if doing so makes any difference.
