Thread starvation or clock leap can be caused  due to different causes but mainly it happens because of below reasons-

• High load on the engine
• The server is so busy that thread starvation is occurring, which is preventing the housekeeper thread from running.
• GC running for a long time.
• Insufficient resources (heap or CPU).

Possible solutions for this issue could be the following:

•  Increasing the memory of the engine.
•  Rebalancing the jobs running on the engine.
•  Dividing a big pipeline into multiple parts.
• Reducing the Batch size
