above is the second time it happened, there was also an error with /datastores.js:60

Did you start a second gekko on the same market?

Just a suggestion ENOSPC suggest that it might be out of disk space?

There is a suggestion here that relates to watching files - possibly running out of disk handles - not sure if that is relevant:
http://stackoverflow.com/questions/16748737/grunt-watch-error-waiting-fatal-error-watch-enospc

Also one here that suggests running out of inode entries can cause it:

"Did you start a second gekko on the same market?"
No, once it errored and stopped the first time, the prompt came back (cd gekko-localDB) so I ran it again (node gekko).
Only diffrence between first and second time:
First time ".../home/pi/gekko-localDB/core/datastores.js:60..."
Second time ".../home/pi/gekko-localDB/core/candleManager.js:898..."

I am running linux on a 4gb partition, so disk space could be a problem. I set it to log 300 historical entries.

what does 'df' give you?

[gr225607]

it gives me:

Rootfs mounted on / 100% used?

you only seem to have a 2GB root partition - 2,721,336 x 1K blocks

Weird.

I'm writing it off as a one time error since I can't reproduce this at all. If it happens again please re open.

@djmuk it's a Raspberry PI with a usb stick (probably).

No a gekko issue -
Definitely disk space issue - he had about 4KB free on his root partition...ENOSPC is exactly that Error NO SPaCe...
