    Posted Thu September 28, 2023 02:14 PM

    You might notice in the logs the following warning message:

    [thread:HikariPool-8 housekeeper] [stage:] WARN HikariPool - HikariPool-8 - Thread starvation or clock leap detected (housekeeper delta=2m06s131ms294µs591ns).

    It indicates a high load on the engine and could be followed by an error java.lang.OutOfMemoryError: Java heap space.

    You should check the CPU and memory usage of this engine.
     
    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.
