Server crash cause of chunk updaters?!

[MrSliff]

Hey guys, we own a little server with 8 slots and 2GB RAM

 

 

today i wanted to make some qcraft portals with a portal point where u can acces all the other portals from

 

i set up approx 4 or 5 chunk updaters (i think they were configured to load 9 chunks each of them), to make the portals to work

 

 

as i was flying around to find some nice portal-spots (i`ve set up 1 already), the server crashed, maybe because of too much chunk load

 

i dont know if this happened because i was flying around or because of the 5 chunk updaters, as 1 is in our hometown, where my mates were around (so it doesnt count i think)

 

 

4 chunk uptaters with 9 chunks are 36 loaded chunks in total by the updaters...

 

 

we were 3 people on the server as this happened

 

 

 

so was it because of flying around (optifine view distance far +32) or because of the chunk updaters?!

Probably because of 2gb ram. Crash reports help locate problems.

ok, i dont know how much ram is recommended for tekkit with 8 slots, were just 4 to 5 players online at the same time

I once heard a rule of thumb is 512MB RAM per player, so maybe you are skirting the limit with 5 or more, and small things will push the server over the edge. So if it remains stable with 3-4 players, RAM would would be my guess, too.

You can try doing that portal thing when you are the only player online. If things remain smooth then, that is a good indicator.

ive tried it this morning alone, but it resolved in half tickrate of the server

 

i spammed portal jumps to several points to run the mp-chunk chache empty

 

 

i put the chunk updaters away, but when the server resumes from standby when you connect after some time it remains in half tickrate -.-

 

 

 

 

weve built several thing atm like a qcraft building and a force field and its getting more and more, i dont know if this is getting the server running slower too

ok restarted the server, were running in normal speed.

 

when i jumped through the portals several times, the server started to lag -.-

I run my client at 5gb of ram and in a lan world with 1 other person it still lags sometime. Also some things are morr resource intensive than others, such as world gen and ME networks.
