Sometime transient threads stay longer on the CPU. Currently, the kernel has no mechanism to detect long-running transient threads. When this condition occurs, a single runnable thread on a CPU's run queue can starve, leading to various issues such as a drop in performance and node eviction.
Workaround: Disable transient threads by setting the following attributes in the /etc/system file:
thread_transience_kernel=0 thread_transience_user=0
