Bus error on Raspberry Pi

[catboy5]

I don't think my Pi is overheating. Everything works fine.
It's very stable

I will try to rebuild

When i try svn up, there is an error:

root@raspberrypi:/home/MCServer# svn up

svn: E000005: Can't check path '/home/MCServer/squirrel_3_0_1_stable/lib': Input/output error
