Sending message trough channel API takes 100 times more time

[Aleksei Rovenski]

Hi all,

We have an emergency in our app (yagoloo-chat). We are using Channel API and about 2 hours ago smt very bad has happened. 

Where it usually took 20-40 millis to send a message through the channel (not delivery time, I mean api method lock time), now it takes 4-5 seconds. 

Yes SECONDS, so when we call ChannelServiceFactory.getChannelService().sendMessage(""), it blocks for 4-5 seconds. We are using queues to send messages, where each task sends 5 at max (can be less) and at the moment it shows 17 seconds average execution time. We also have appstats enabled which clearly show sendMessage() eating the time.

Needless to say our instances have skyrocketed, where usually we had 2-3, now there are 16. We are not paying for premium support, does it mean we will have to pay for that??!

Please someone at google take a look at this. I have filed production issue...

cheers,

Aleksei

hi,

The Channel API service should be back to normal now, as updated in the links provided earlier in this thread:

 https://groups.google.com/group/google-appengine-downtime-notify/browse_thread/thread/d93284e4240a9352

I don't know if it's the same issue but my application is also encountering bugs with the channel API

When I call: channel.open() the message below is displayed in my browser:

"Failed to load resource: server responded with a status of 400 (Unknown SID)"

As a consequence, my users can't see the other connected users. That's really damaging their experience. 

Thanks for looking at this problem
