@MattWho No, no WARNINGS OR ERROR in the log files. I dont see any out of memory issues as well. However, I have gotten the diagnostics file and I am attaching it in the reply. Can you please look at it and give me any clue to further diagnose this queuing issue?

@MattWho I tried to increase the thread count but the issue still persists. I was able to locate one queued file in the logs and I am pasting it under: this particular flowfile got queued and never processed despite having 30 minutes gone. Its merely a 1.4kb file.

Thanks for replying @MattWho. Yes, Max Timer Driven Thread pool is set to 10 by default. At one time, around 10+ processors run in a single proccess group. Moreover, the Flowfile is indefinitely queued until I manually stop the next processor and then start it again. Once I start it, it smoothly migrates the data. I have not checked the logs, I will do so now.

Hi all, I have been seeing this problem increasingly now that the data gets stuck in between two different processors -- the data being as small as few KBs what could be the cause of it? The ExecuteSQL contains an SQL insert script. Moreover, this behavior is random -- occurs randomly on any processor. Does my machine specs count in this? I see my CPU usage and memory are not choking as well. Any comments on this will be appreciated. Thanks

I am also having these erros, if it helps you in any way.

The NiFi actually starts for the first time, if I close it and try to restart it, it never gets restarted again. No custom add ons. I dont know how to debug in logback.

I have extracted below json from my executesql processor: { "Id" : "B2606868-F4BC-4230-9749-A083F6D222B2", "ReminderPlan" : "-5d, -1d'", "ModifiedOn" : "2024-01-03 19:56:59.0000000" } and I have several of these. The task at my hand is to extract the reminderplan value and pass it as an attribute to some sql processor and run a sql function on that reminderplan column value; for example: DECLARE @output varchar(255); SET @output = NewDemo.dbo.StandardizeReminderPlan('-5d, -1d') SELECT @output AS Result; After storing output value in Result, I want to insert the function value back in the same json. Could anyone suggest which processors I should use to accomplish this?
