KDB process unable to process request

Community Support

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,
