Is there a size restriction on KML layer in esri map?

[DamNguyen]

My website utilizes ESRI's map and it contains several KML layers. Most of them show up fine except for the ones bigger than ~4MB. Are there any restrictions on KML file size?

Thanks,

I don't know specifically about KMLs & the JS API but here's a link to the limitations of using KMLs with Arcgis.com:

KML Limitations

Perhaps these limitations also apply to KML layers within the API..

Thanks, evtguy. From that page, I see this relevant bit:

KML layers larger than 10 MB cannot be added to maps.

I tested it with ~4MB files (individually and cummulatively) and they still aren't showing up. Could it be that the limit is <4MB?

Unfortunately, someone from ESRI will have to chime in about this. The only KML files I have personally dealt with using the JS API have been VERY small (< 100kb).
