Push hangs, error on pull
Opened this issue · 8 comments
Drive hangs when I try to push a file, using about 100% of one CPU core, and when I run drive pull I get the following output:

I am using a clean install of Lubuntu 14.10.
I am having issues with drive hanging when I push and hogging a core. The file I am pushing is almost 2GB. How big is the file you are pushing?
The issue occurs for me even when I push a file that is only a few bytes.
see http://stackoverflow.com/a/12844718/558774 if it clarify your situation. "you are probably hitting address space limits", means system can't create more threads because of shortage of RAM. you should post some detailed report of resources available on your machine at the time you run drive. also, you can try to sync only one file at time from that machine.
It's a 32-bit system with 1GB RAM, of which about 800MB was free at the
time of launching drive. It has no problem running Firefox, so it should
presumably be possible for it to run drive.
I've hitting the same issue (I've had it from diff, pull and push). I have 8G of RAM and the machine is doing very little else. From some other searching, it may be that there are too many threads, caused by too many goroutines. The stack trace I got has 606 goroutines in it. Also, sometimes the the commands work just fine. So it seems like some kind of random element is involved. Perhaps if the network is fast the goroutines complete quickly and don't accumulate but if it's slow, the backlog builds up and eventually exceeds a thread-limit.
(I'm on Ubuntu 14.04)
@fergald I recommend you using this branch: https://github.com/odeke-em/drive. Emmanuel did serval significant improvements.
I already am :(.
Should I reopen this bug on the other project?
Ah, already there.
