Re: [squid-users] Strange High CPU usage

I am using 2.5STABLE3

I have a same problem over here. I have set half_closed_clients to off in
squid.conf

client_http.requests = 210.684248/sec
client_http.hits = 126.796477/sec
client_http.errors = 0.000000/sec
client_http.kbytes_in = 135.014952/sec
client_http.kbytes_out = 1410.308364/sec
client_http.all_median_svc_time = 0.092188 seconds
client_http.miss_median_svc_time = 1.542425 seconds
client_http.nm_median_svc_time = 0.012346 seconds
client_http.nh_median_svc_time = 1.628034 seconds
client_http.hit_median_svc_time = 0.024508 seconds
<snip>
select_loops = 64.277153/sec
select_fds = 1312.027761/sec
average_select_fd_period = 0.000756/fd
median_select_fds = 16.933594
<snip>
cpu_time = 281.290000 seconds
wall_time = 300.055655 seconds
cpu_usage = 93.745942%

I have less than 5 acls's in my configuration.
