Error When Starting Server

Hello,
I have looked through many forums and found some troubleshooting tips, but after following what I could I am still encountering the same error. When trying to start my server I am seeing the following in the error logs. I know I ran out of space, but I deleted a number of old restore points and archive and have over 50% available now. I have also removed jar files and redownloaded the profile in order to recreate them.
Any help would be appreciated.
Thanks!
