Hi all !

I am running PostgreSQL 7.3.2 on Linux 2.6.13...

What I see when VACUUM process is running is:

Cpu(s):  0.0% us,  3.2% sy,  0.0% ni,  0.0% id, 93.5% wa,  3.2% hi,
0.0% si

What I am worry about is "93.5% wa" ...

Could someone explain me what is the VACUUM process waiting for ?

Best regards
David
