I am experiencing very strange apache behavior on the server. Server : FC2 / PSA 7.5.1 Sites : only 2 Server load go up to 45.00 But decrease to normal > 1.00 , when I disable the domain in the PLESK. But even if I disabled the domain, the domain is available on the net. My programmer has installed another session of apache on the server which is using another port. But I am not sure that has anything to do with this. Any help from experts?
