    What’s your memory settings?
    you have a memory leak somewhere, check the running services and take a thread dump.

    Also check your transactions table to find any bulk insertions took place during that specific window which is worth to check.

    Thanks,

    First check your memory max settings also during the time it might have created java heap and core files in the IS directory did you see it any IS hung?

    Assuming you IS version is 712?

    It is the settings for IS JVM memory how much min/max to use (gives life to IS performance)

    What is the issue you are facing here? Is your IS behaving slow?
