Getting a out of memory error...

[fstltna]

I have it set up but when starting it I get this:

INFO[0000] Starting mapserver                            version=3.0.0

fatal error: runtime: out of memory

Any ideas?

Strange, it should not consume that much memory...
Can you tell me something about your setup:

• Map-size
• Map-type (sqlite/postgres)
• RAM-Size
• Operating System

If it is possible could you provide a reproduction-world to test on?

Also: can you try to run in debug mode and post the results here afterwards:

mapserver -debug

Ok, I'm not sure of the map size, but I am using sqlite, RAM is 1GB, OS is Ubuntu 16.04. Attached is the debug output...
mapserver_debug.txt

That may be related to:
https://github.com/thomasrudin-mt/mapserver/blob/master/doc/config.md#mapblockaccessormaxitems

Can you try setting the limits in the config file a bit lower:

mapserver.json

{
	"mapblockaccessor": {
		"expiretime": "5s",
		"purgetime": "10s",
		"maxitems": 100
	}
}

Those essentially control how many mapblocks are cached in-memory.
The default is 5000 mapblocks, a setting of 100 should work but is slower during the initial rendering.
