server will not start or restarts right away memory issue?

[Blue]

Hi frist off i dont think this is a issue with FTB or any mod packs

i was wondering if some one can guide me if my issue im having is with memory this is my command start line with my hoster, that i can not edit

-Xmx5120M -Xms100M -jar direwolf20.jar nogui --nojline

and this is one of the errors i managed to spot right before a crash or restart

----------
im on a 5gig server rental plan but i been noticing here and there out of memory in my logs when they manage to generate

I just want to rule out memory issue and not becuase im adding extra mods on top of it...but all these extra add on mods will work on my PC just fine so im at a lost

Thanks for the help!

You are out of PermGen, use the server JVM arguments found here: http://forum.feed-the-beast.com/threads/jvm-arguments-for-modded-minecraft-updated-11-11-13.28994/
