redis driver _get_lock set lock_key problem

Correct, they should have separate session IDs.

However, it's also important how much time these requests take to process. One hung request would block all subsequent ones from the same device, and you'll accumulate a lot of them with 1 per second.

Hi,

the duration of one request is 70 ms.
The ajax requests are on a long poll basis - every request is waiting until the previous request has been completed.

What i found out is, that it could be a problem with loading images... Every image is getting its contents via .php url. There could be problems with redis while loading the image data and ajax calls meanwhile. Tests with session_write_close() at these points are running...

Thanks a lot
