Disappearing Data on Map

I'm having a weird issue where lines in my map disappear depending on what area of the map I'm looking at.

Unfortunately the map is on a development machine but I am able to move it if it helps people. There are no javascript errors or anything.

Map with data showing:
[ATTACH=CONFIG]23382[/ATTACH]

Panned a little bit to the south (Same month, same map):
[ATTACH=CONFIG]23383[/ATTACH]

And all the data looks fine in ArcDesktop:
[ATTACH=CONFIG]23384[/ATTACH]

Does anyone know what could be happening or how I would find out what is happening?

featureLayer? if so, what is the draw mode? can you see any failed requests in the network traffic (use browser developer tools) perhaps you've hit the default limit of features ArcGIS Server will return?

if none of these suggestions help, taking a look at the live site would probably be helpful

It's a dynamic service and there's no failed web requests in the network traffic.

I think I just figured out what the problem (or one of them was). I thought to check the log files for the service on in the server manager. The service was throwing an error "There is an error during the draw: %s (1.) OID mapped column has null value". After setting the unqiue ID field properly the data seems to be mostly there now.

I'm getting another issue of "There is an error during the draw: %s (1.) The number of points is less than required for feature" but I seem to be on my way to figuring it out.

Thanks for the help though! Much appreciated.
