  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
