    <p><em>tl;dr: No idea on the cause, posting random possibility in hope it might give someone else an idea or two for testing.</em></p> <p>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 &amp; 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.</p> <p>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:</p> <p>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 &amp; 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.</p> <p>Things you can experiment with:</p> <ul> <li>Reduce size of app to see if page can be reloaded more often (as suggested by stackfish)</li> <li>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?)</li> <li>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)</li> </ul> <p>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 :/</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
