[hobbit] Loss of Apache graphs

[Thomas]

Yes thats right, mine are usually around 2 GB when I get into problems, 
so this is not it. Also I done have this in my logs

2006-02-09 15:24:36 Tried to down BOARDBUSY: Invalid argument
2006-02-09 15:31:54 Could not get shm of size 262144: No such file or 
directory
2006-02-09 15:31:54 Channel not available

so something else is wrong.
