please note WaitQ: 854

please increase
lsws web admin -> Server -> General -> PHP suEXEC Max Conn: 10
for example, 50, then see if WaitQ will reduce to 0.

maybe you're under DDos ?

please try:
lsws web admin -> Server -> Security -> Per Client Throttling :
Dynamic Requests/second: 1
Connection Soft Limit: 3
Connection Hard Limit: 5
Block Bad Request:Yes

don't touch settings here, best to revert to default values.

increase "Banned Period (sec)" if DDos continues (under Per Client Throttling)
