So I start up htop and I see a process starting to using 200-300% of the processor and eating up more and more memory.  When I killed the Gnucash app, it was approaching 8GB RAM and 15GB Virtual memory.

It doesn't have a copy of my signing certificate on it (I travel with it and don't want to risk compromising the certificate if I lose it), so that isn't why. I don't think I've ever seen it take more than a few seconds for any app. CoreServicesUIAgent is apparently the program that does the verification, so it's no doubt what's at fault, but it's an Apple program, not something I can do anything about. It does seem unlikely that Apple would want to hang regardless of what it's fed, but they're likely to tell you to upgrade to 10.11 and try again if you report it.

Thanks John,

I tried to recreate the problem that happened a few days back which I 
reported.  I downloaded 2.3.11-1 Intel again and installed in /Applications.

This time I collected all the data but didn't force quit Gnucash after 
it appeared that the verification window hung.

It took a little over 4 min. for verify to complete.  Then 2.3.11-1 
opened.  It looks like everything is OK now.  It will open multiple 
times and within a second now.

I have captured a video screencast, collected samples from Activity 
Monitor if this is of any help.  Please just let me know.
