Hello Community,
i’m using two robots to treat a large mass of queues, normaly if a robot start a queue automaticly the status change from new to In Progress … but sometimes … i found out that the both robots take the same queue.
how this can be possible if the orchestrator is taking charge of this!!
Waiting for your reply.
Thank you.

Welcome back to our UiPath community.
It shouldn’t read the same item.
May I know are you using Get Transaction Item or Get Queue Items activity ?
Get Transaction Item
Both taking the same item.

Hey @bouhia
Are you using orchestrator for this ?
And from where did you pick this logs ?
Thanks

This items is treated by two robots
yes im using Orchestrator
This log is made by me with ReFramwork.
Hi @bouhia,
This is classical queue behaviour.
From your screenshot it is evident that first the Robot03 dispatched the item. Later the item was picked up by your performer/Robot01, which first set it to in progress, completed the transaction and set status to Successful.
Take this example:
If we for some reason had a retry and you have both robots actively working the queue. The retry item is then defaulted to a new item and both robots try to lock it into in-progress but only one of them can takeover the item. This is the round robin algorithm in the working. Read here for an quick overview.
So the thing you observe here is totally normal and as it should be.
but the execution was done by both robots, the proof is the logs generated by the process during the activity of each robot
Yes of course I agree with the logic of this algo, but in my case I had this anomaly.
In that case are your sure that your queue is entirely without any duplicates? If the dispatcher for some reason has sent the same item two times to the queue, it is possible that both of your robots had to process the same Order ID.
there is no duplicates on the database, also in queues … whats made the both robots take the same line
