Reloading Flash 17 times causes error #2046 and requires a browser restart

Disclosure: I am a Flash Player Developer at Adobe. This is unlikely to get much attention as it is Linux only and kind of an edge case: Probably annoying during dev work but very few users will reload the same page more than 16 times. It might also be a browser issue. But it is probably us :) I will look at the jira tomorrow and see if I can bump it up a bit, but I'll be honest in that it is really an edge case and unlikely to get much love. If you want to increase your chances make sure to add the most simple .swf test case you can make to the bug. Also please double check if it still happens with the latest beta. I also just took a look at the earlier bug reports and forum posts, you probably should post this as a Flash Player bug, not as Flex.

Long shot guess, but it sounds similar to a problem we had.... in the project properties - Flex Build Path - Framework Linkage - change to "merged into code". This fixes a problem very similar to what you are describing, though I wish I knew exactly what the cause is. Good luck!

tl;dr: No idea on the cause, posting random possibility in hope it might give someone else an idea or two for testing.

Considering that it seems to be an unresolved bug in Adobe issue tracker, its unlikely that you will get any definitive answer here. Considering it occurs on both Firefox & Chrome, let's rule out browser bugs and assume it is in either some common library (Flash) or OS API (Linux kernel implementation). A comment in one of the jira issues specifically mentions killing Flash process fixes it, so its a Flash issue and not OS bug.

The most interesting thing I can see here is your observation that it succeeds for exactly 16 times before failing to load. Time for some speculation here, from someone who's never worked on kernel or crypto dev:

With a 2048 bit RSA key and 32k cache for storing them, 16 keys would fit before adding another one fails - so one conjecture is that each time this file is loaded, Flash is caching the signed value (possibly a hashed version) for some reason - maybe to keep track of allowed & used security permissions etc.? If this entry is not removed, then once it is full all file loads will fail if caching the signature is part of checking it.

Things you can experiment with:

Reduce size of app to see if page can be reloaded more often (as suggested by stackfish)

Count number of signed RSLs used and if its a power/multiple of 2 (maybe others get the error after 32 page loads if they use half the no. of signed libs?)

Check if Linux Flash plugin has some option to increase credentials cache or something (or decrease it, just to see if it impacts the no. of loads - if so, could be related to the problem)

I expect that to actually find a solution, you'd have to dive into the library loading code and look at all constants related to loading signed libs that are 4, 16, or a multiple of 16 to see if they might be responsible - in short, unlikely to be soluble by others outside of Flash dev team imho :/

This behavior could be related to a memory leak caused either by the Flex implementation, or the browser plugin. Firefox is notorious for not cleaning up memory anyway and the footprint will continue to grow the longer you have the same browser window open.

If you reduce the size of your flex app to produce something very tiny, does the number of times you can reload the page go up?

I meet a same problem when I use ppt on icourse163.org . when I open the course site, I can't see the ppt but I use chrome can do it .there are the same flash version(32.0.0.344),and Then ,I copy the tar.gz file that downloaded from adobe. usr/* to /usr.I solved it.wish can help you .
