Okay, when trying making a local server, I have memory issues like I put 2G for the server, I have 8G of RAM, is this very common for a server machine to do this? I also have "can't keep this up" server error
depends, if its permgen memory error then yes very very common, and easy to fix, look at step 6 on

2 gig is also very small for a pack this large, i recommand 4 but you can possibly get away with 3.... never tested it with 2, so that may well be your issue if its not the permgen
"cant keep up, did the system change the time?" means the server is getting stressed, you will often find that when terrain generation is going on or in the first 10 minutes - hour of a server loading up. (or if your trying to host a server and play on the same machine lol*) nothing really can do unless you want to start disabling mods, tbh do a couple of tests
1 do /tps in game, 20 is perfect, over 15 is ok, 10 to 15 your gonna notice, under 10 is bad
what is this? well its ticks per second, there is 20 ticks in a second on a perfect server (its what i aimed for on the test server and was able to maintain with this pack) everything takes x ticks so when the tps slows down other stuff does to, example: when you place a bucket of water against a cliff face you create a source block, it then creates a flow block under that if theres air and do does that and so on untill it hits the floor, you will see the speed difference on a low tps server.
smash a block and see how fast it is between the blocck breaking and the pickup dropping (this is known as block lag) if its instant then dont worry too much
* if your hosting and playing on the same machine, the number one reason people do this is to play with a mate who is not on your network, easy fix, open up a lan game it will tell you the port thats in use (sadly random every time) write down that port and port forward it on your router, give your mate the server address of yourPublicIp:thatPort (its how me and my livestream co-host played better then wolfs ...way way back)
Good luck
