High CPU in InternalInputBuffer.nextRequest after updating to 6.4.13

Solution Verified - Updated -


  • We recently updated to 6.4.13. Afterwards, we often see high CPU in threads executing the following:
"http-" #173 daemon prio=5 os_prio=0 tid=0x00007f0160056000 nid=0xd06 runnable [0x00007f017d350000]
java.lang.Thread.State: RUNNABLE

  • Randomly despite almost daily jvm restarts we detect saturation of the CPU
