Hi [~wilfreds]. Please correct me if I am wrong. When a large number of node
heartbeats trigger scheduling, the continuous scheduling thread will be starved
because lock conflict.
{quote}The side effect is however that when a cluster grows (100+ nodes) the
number of heartbeats that needed processing started interfering with the
continuous scheduling thread and other internal threads. This does cause thread
starvation and in the worst case scheduling comes to a standstill.{quote}
