It's not the md5 hash collision that I'm worried about. But when a pair of certs become available, how does the server ensure there will be no two (or more) clients downloading it at the same time? Due to high demand, there is a high probability that one client connects while another client download is in progress.

first come first serve basis.
Once the unique cert is handed out, it will be deleted immediately.
The server answers to each wget request and sends back to one source

Which means the cert may not be deleted quickly enough. Unless the server makes sure to prevent concurrent downloads for the same cert. This is what I'm trying to establish here: are the certs really unique, or almost unique?

I'm checking with anethema on the server side, I will let you know to see.
As far as the certs being generated, they are 100% unique.

Just reporting back from using the push certs provided by this and I can confirm it works great

However, today I opened an app using push and was greeted with this message:

(not my picture, I found it on google, but that's the exact message)

I tried opening the app several times and still got the same message so I thought I'd leave it for a while, checked back in 30 minutes and it was fine...strange! I also got the message once yesterday too but ignored it and the next time I checked it was fine again so it didn't really bother me.

Can anybody shed some light on this intermittent issue?

There are some cydia programs that can screw up push notifications.

SBSettings Push Toggle and AutoSilent both are known to cause this problem.

The fix is documented here: Twitlonger: @pushfix might have found the solution to the 'plug into iTunes'. It has worked for 3 people so far.

@dborca,
"anethema" got back to me.
Duplicate download were very unlikely before, but since you've raised the question, PHP has been completely re-written and therefore it's now impossible for it to happen
Let me know if you have any other questions.

Thx

Hi! I badly want to use push doctor but I have Autosilent installed and i'm scared after reading the above thread. What problems am I likely to face if I still go ahead and what is the REMEDY.

Thanks a lot for your input and help with the push issue.

The fix is simple. Problem will come back until you either stop using autosilent or if possible just disable the feature that silences push notifications.
