#3430 – Google Photos Import Generates Deadlock

 I used the Google Photos Import Button last weekend to import 257 albums into Event Gallery.
As advertised it took a long time, but I also got a messages that a deadlock was created and was advised to try again.
All of the website operated as normal at that point with the exception of Event Gallery.
If I tried to open Event Gallery it took a long time and after that I got the Deadlock message again.
Finally the problem disappeared and when I went to Event Gallery I noticed that the import had run perfectly.
So this again is not a big deal, but I thought you should know.
Best Regards
Frank Bertram

"deadlock" is the wrong term I guess. You get timeout errors, right? 257 Google Photos albums are a lot!! How many images do they contain? With the Google Photos API a lot of requests are necessary to retrieve all the information and that API is very slow.

So far I don't have a solution for this. I need to query the information at some point in time. A cron job would work but I don't think regular users can set that up.

Hi Sven,

>>>>"deadlock" is the wrong term I guess
I agree, but that was part of the error message I got.
Unless there is something very very smart built in there is no way the system can tell the difference between a time-out and a dead-lock.

So do not worry Sven, in the end I got all the albums I wanted.
And what is more your Component runs fantastic, it seems to have not much difficilty with lots of photos.
I have not counted recently but there must be approx. 3000 photos.

Shall we close this ticket or is there something you'd like to do.

Best Regards.

We can close this ticket.

If you have many albums, please keep an eye on the daily requests to the Google Photos API ( on the bottom)
