No. cache.log is usual log and no symptom is in that file. When this problem occurs, cache.log is not updated. I think squid process repeatedly occupies cpu0, cpu1, cpu0 .... because cpu load is 50%. Mutex lock is related to this problem(or other OS env)? # vmstat 3 procs memory page disk faults cpu r b w swap free re mf pi po fr de sr m0 m1 m3 m5 in sy cs us sy id 0 0 0 2119616 459016 38 149 105 42 35 0 0 0 0 49 1 653 1014 992 7 5 88 0 0 0 729896 270160 8 53 0 2 2 0 0 0 0 0 1 262 277 326 50 1 50 0 0 0 729896 270168 8 51 0 0 0 0 0 0 0 0 0 263 681 330 50 0 50 0 0 0 729896 270168 66 187 0 0 0 0 0 0 0 0 0 231 1488 321 50 1 49 0 0 0 729896 270168 8 51 0 0 0 0 0 0 0 0 0 234 385 313 50 1 49 0 0 0 729896 270168 8 51 0 2 2 0 0 0 0 0 0 258 411 331 50 0 50 0 0 0 729896 270168 14 88 0 2 2 0 0 0 0 0 1 262 529 341 50 1 50 0 0 0 729896 270168 66 187 0 0 0 0 0 0 0 2 5 320 1686 394 50 3 47 0 0 0 729896 270160 8 51 0 0 0 0 0 0 0 0 0 248 300 319 50 1 49 0 0 0 729896 270160 8 51 0 0 0 0 0 0 0 0 0 255 289 327 50 0 50 0 0 0 729896 270160 66 187 0 0 0 0 0 0 0 0 0 307 1528 347 50 1 49 0 0 0 729896 270160 8 51 0 2 2 0 0 0 0 0 1 230 330 306 50 1 50 0 0 0 729896 270168 8 51 0 0 0 0 0 0 0 0 0 246 424 324 50 0 50 0 0 0 729896 270168 8 51 0 0 0 0 0 0 0 0 0 227 347 315 50 0 50 0 0 0 729896 270168 66 187 0 2 2 0 0 0 0 0 1 236 1517 314 50 1 49 0 0 0 729896 270168 8 51 0 0 0 0 0 0 0 0 0 290 515 356 50 0 50 0 0 0 729896 270168 8 51 0 0 0 0 0 0 0 0 0 277 369 347 50 1 49 0 0 0 729656 269616 66 187 0 0 0 0 0 0 0 3 1 298 1579 369 50 4 45 0 0 0 729896 270160 8 51 0 0 0 0 0 0 0 0 0 264 325 329 50 0 50
