Default strange load problem on freebsd 7.0 amd64

System has dual Xeon quadracore, totally 8 CPU and 16 GB ram.
Problem: load average periodically is somewhere 20-30, and server is freezing. But in same time, only 1cpu is used. Running processes is many small fastcgi/php-cgi, so there is not one resource hungry process.

from top:
last pid: 99483;  load averages: 23.82, 17.13, 14.08    up 6+19:09:32  16:22:11
913 processes: 2 running, 910 sleeping, 1 zombie
CPU states:  9.8% user,  0.0% nice,  8.0% system,  0.4% interrupt, 81.8% idle
Mem: 3006M Active, 10G Inact, 689M Wired, 476M Cache, 214M Buf, 859M Free
Swap: 4096M Total, 12K Used, 4096M Free
