I am a bit worried about my linux vserver box.
No more memory is left.
To investigate this issue, i was looking at "top". But it deeply confuses me.
It seems that no more memory is left, altough the process list in top never adds up to 100%
top - 13:39:05 up 10:46, 1 user, load average: 0.08, 0.02, 0.00

Cpu(s): 20.5%us, 1.8%sy, 0.0%ni, 77.5%id, 0.0%wa, 0.0%hi, 0.2%si, 0.0%st

free also thinks no more memory is left
