    KDB process unable to process request

    Posted by k-mambo on April 17, 2022 at 12:00 am

    Sometimes, the HDB process that queries historical data becomes unable to process requests.

    It does not appear to occur periodically and the values for RECV-Q do not change over time.

    Timeout is not an indefinite period of 60 seconds.

    Is there a way to determine whether a request is currently being processed or how many synchronization requests are waiting for a process executed in the background? I want to know if there are enough requests waiting for the process to process.

    Is there a way to debug these problems efficiently?

    Hello,

    The KX IPC documentation found here

    highlights the role that the .z namespace plays in IPC and specifically here presents .z.W

    .z.W returns a dictionary where you can see how many messages and their size that are queued on a handle.

    Hope this helps,

    Leah
