Error: write EPIPE and 0x03 error exporting image

[markathomas]

Expected behaviour

Chart is exported correctly

Actual behaviour

Export returns no image

Here's from the log file:

This is after the upgrade to master branch with the Express upgrade.

Here's another error that's popping up:

Any news on this? I'm getting a very similar error, but with 0x04 code when running as a Node.js module:

This happens about 1 in 5 times on the same exact chart, other times it finishes the export just fine.

One thing to note - this seems to happen more often on charts with large data sets (over 100,000 points). This somewhat leads me to believe that it's some sort of timing issue...

Tagging @cvasseng just in case he missed this...

After further examination, I don't think my issue relates to this. I have outlined my problem here: #171
