Arch Killing long running node/npm processes before finishing - faddah - 04-28-2016

hello all,

when i run certian longer processes in node.js/npm, like an update ($ npm update -g) or to search for an npm package ($ npm search elm), it starts the process on my Pine64 A64+ w/ 2 GB board, but then half- or even three-quarters of the way through, it just kills the process before it completes; particularly, i noticed, when it's waiting for info to come back across the 'net through the ethernet port, with —

Killed

then it just gives me the command prompt again, process never completes. this happens no matter how many times i re-try it.

is there anyway to change a setting, somewhere, that will extend the amount of time before these processes are killed? any help would be much appreciated, please. thank you and advance. 

best,

Can you please provide the output of 'uname -a' and 'cat /proc/meminfo'

Thx for the answer. The OS image you're using is obviously only able to recognize 1 GB RAM (know issue, fixed by longsleep ages ago) and also the kernel is rather outdated. By simply executing the three lines below you get 1 GB more useable DRAM, a fixed MAC address without any hassles and a bunch of other fixes for free.

Unfortunately the Pine64 folks do a really really bad job providing necessary informations (maybe for a reason? Marketing matters) and all you need to do is to update both u-boot and kernel.

Please read through these instructions:

- http://forum.pine64.org/showthread.php?tid=737
- http://forum.pine64.org/showthread.php?tid=293

TL;DR: To update any of the available OS images all that's needed is just the following executed as root followed by a reboot:

Code:
bash <(curl -s https://raw.githubusercontent.com/longsleep/build-pine64-image/master/simpleimage/platform-scripts/pine64_update_uboot.sh)
bash <(curl -s https://raw.githubusercontent.com/longsleep/build-pine64-image/master/simpleimage/platform-scripts/pine64_update_kernel.sh)
bash <(curl -s https://raw.githubusercontent.com/longsleep/build-pine64-image/master/simpleimage/platform-scripts/pine64_fix_whatever.sh)

It's a shame that such essential information isn't provided at the download location where every new user searches for software.

Regarding your real issue I would suspect reading through 'man nohup' should be able to solve the issue? Smile

Linux doesn't normally kill processes that run long. Try "dmesg | tail" after the process is killed to see if something like oom is killing it.
