it should be reproducible but Deep was unable to reproduce using the UI because it does not allow invalid map function.
from Deep,

Tried this on Linux(centos) for build 2.0.1-160-rel and 2.0.0-1976-rel.

If I create a view with below map function:

Leader board
function (doc, meta) {
  if (doc.jsonType == "player" && doc.experience) {
  emit(doc.experience, null);
  }
}

I get the below error on saving it:

"Syntax error in the map function of the view `v1': SyntaxError: Unexpected identifier"

I just have a default bucket on 4 nodes with 1000 json docs in it.

Tried with gamesim-sample bucket as well. Added a new view to it with above definition. Getting the "syntax error" message there as well.

Sharon, so the "Leader board" is part of the function? Is that the syntax error? Can you please tell us how you created the function? I also can't reproduce it, even through the HTTP you can't add invalid functions.

yes, it's part of the function, i.e. expecting a syntax error.

to be clear on the details,
i installed 3 nodes cluster via rightscale on EC2, run the load of the gamesimulator itself (not the sample bucket) and had ~400K documents.
i created this view while load was running. and then the node crashed.

doesn't the collect info show this crash clearly?
it happens to me all the time. i never saw this syntax error message on a cluster, i'll try it on my macbook later on.

Sharon, any news? Can you reproduce it on your MacBook? It could be a serious issue if it can be reproduced.

Unable to repro with build 2.0.2-764-rel and 2.0.1-170-rel. Tried on a 3 node cluster on Centos 64. With the load running, created the view with javascript error. It gives syntax error. No crash observed.
Tried creating the bad view with indexing/compaction/mutations running in parallel. Syntax error is always returned.
