[registery]

i have strange problem here. this is usign high cpu usage. how can i find what cause this. thanks

poll([{fd=129, events=POLLIN|POLLPRI}], 1, 0) = 0 (Timeout) clock_gettime(CLOCK_MONOTONIC, {7158998, 110383876}) = 0 clock_gettime(CLOCK_MONOTONIC, {7158998, 110551255}) = 0 clock_gettime(CLOCK_MONOTONIC, {7158998, 110609750}) = 0 select(130, [129], [129], [], {15, 0}) = 1 (out [129], left {15, 0}) poll([{fd=129, events=POLLIN|POLLPRI}], 1, 0) = 0 (Timeout) clock_gettime(CLOCK_MONOTONIC, {7158998, 111045572}) = 0 clock_gettime(CLOCK_MONOTONIC, {7158998, 111210986}) = 0 clock_gettime(CLOCK_MONOTONIC, {7158998, 111339558}) = 0
