situation. Compare the strace output when it's behaving reasonably<br>
versus when it's taking excessive CPU time, to see if there's any<br>
difference in the kinds of file accesses or system calls.<br>

<br>The above lines from high cpu usage are in addition to the ones below when normal 0-2% CPU is being used. Maybe there is significant data outside the same I took since I only compared about 100 lines of the strace. <br>
<br>Both have entries like the following:<br>clock_gettime(CLOCK_MONOTONIC, {263050, 270597399}) = 0<br>read(8, 0x25ea604, 4096) = -1 EAGAIN (Resource temporarily unavailable)<br>poll([{fd=4, events=POLLIN}, {fd=9, events=POLLIN}, {fd=8, events=POLLIN}, {fd=12, events=POLLIN}, {fd=30, events=POLLIN}], 5, 0) = 0 (Timeout)<br>
read(8, 0x25ea604, 4096) = -1 EAGAIN (Resource temporarily unavailable)<br>clock_gettime(CLOCK_MONOTONIC, {263050, 270810253}) = 0<br>clock_gettime(CLOCK_MONOTONIC, {263050, 270862210}) = 0<br>read(8, 0x25ea604, 4096) = -1 EAGAIN (Resource temporarily unavailable)<br>
poll([{fd=4, events=POLLIN}, {fd=9, events=POLLIN}, {fd=8, events=POLLIN}, {fd=12, events=POLLIN}, {fd=30, events=POLLIN}], 5, 0) = 0 (Timeout)<br>read(8, 0x25ea604, 4096) = -1 EAGAIN (Resource temporarily unavailable)<br>
clock_gettime(CLOCK_MONOTONIC, {263050, 271074225}) = 0<br> <br></div></div>
