AdWords Java SDK - Getting DatabaseError.CONCURRENT_MODIFICATION

[Stepanian]

Yesterday I started getting a DatabaseError.CONCURRENT_MODIFICATION error for operations that are part of a tool that I have developed and used for months. The tool creates an ad group and then (sequentially) adds criteria to it. There are no multiple threads accessing the API at any given point time. The error comes up at different parts of the process, so there is really no pattern. In fact, in one case, it appeared in the first step the tool was initially creating an ad group!

Has anything changed as far as concurrent modification monitoring in the API itself? Is this something that could be an issue that you may be addressing?

Any guidance would be helpful. Thanks!

Hi Raffy,

The DatabaseError.CONCURRENT_MODIFICATION error that you encountered could occur due to multiple processes that are trying to update the same entity at the same time. It includes a user in the AdWords web interface that is updating the entity while you are updating as well via the API. Can you retry the request again and check if you're still encountering the error? If so, please provide your clientCustomerId, and complete SOAP request and response logs so I can further investigate the issue on my end. You can send them via Reply privately to author.

Thanks,

Luis

Luis,

 I work with Raffy. We are getting this error on adgroup creation in some cases. How is that possible?

Thanks

This is happening also to my application. It was working in this last year very great, from today no.... mmmmh!

Same issue here (using the PHP SDK). We haven't made any modifications and starting yesterday we are experiencing the same issue.

Hello All, 

To be able to troubleshoot on our end, could you please share the SOAP logs along with your CID from one of the requests that failed with this error? You could use reply privately to author while sharing the details. 

Thanks,

Hi,

We have experienced the same issue. We have created an application that uses the C# Adwords API to create adGroups and keywords in a sequential manner (without using different threads).

Until now, everything was ok, but recently the creation of some keywords fails, in a randomic way, due to this DatabaseError.CONCURRENT_MODIFICATION error.

Hi,

The team is still currently working on this. I will provide updates once available.

Hi, any update on this? I think we are a lot of people experiencing the same problem. 

[Sreelakshmi Sasidharan (AdWords API Team)]

Hello,

We don't have any updates yet. The team is currently working on this. I will keep you posted as soon as I hear from them.

[Sreelakshmi Sasidharan (AdWords API Team)]

Hello All, 

Could you please confirm if you are still facing CONCURRENT_MODIFICATION error while making calls with the AdWords API? 

[Jim Malone]

The problem appears to have resolved itself for us.  Can you let us know what the problem was, and if there's anything we can/should do on our end to avoid it from happening again in the future?

Hello,

There was an issue which is currently addressed. If you still see the errors and if you are not making concurrent changes to the same entities (in which case the error is expected), please let me know.
