Hi Harbs,
Btw, I didn't get the context, can you remind me why you need to debug it via fdb, why not directly importing the source as a project, maybe it's what you did, I'm not sure, can you tell me ? If the sources are opened or if you can send me something, I can give a try if you like.

Dunno. I have six pinned tabs in Firefox that are always open, and the app 
starts at the 500 MB range. When I was testing I had another few tabs open, 
but it's nothing that ever gave me trouble before.



Yeah. I think I'm done for now as well. I'll keep my eye on this to see if 
anyone has useful input…

Historically, when browser memory usage gets up past 500MB things get 
creaky

fast.  If you slow down the loading, how quickly does it get up there?
500MB is quite a bit of memory.

There's a module that gets loaded later (debug size of 372 KB). That also
takes roughly the same amount of time.

And without the debugger the loads go quickly?  Do you have time to try

loading 200Kb SWFs with a large image instead of fonts?  Maybe it has to 
do

with fonts somehow.

Actually, now that I'm checking, they rarely go over 200 KB.

No. It seemed to stay pretty constant. If it grew, it was slight. 
Nothing

drastic here.


When you changed the fdb script to add more memory did you then 
test

from

command-line FDB or from IntelliJ?  I don't know if changing the 
script

will
affect IntelliJ.



I tested in both. The results were pretty similar.

For every one it takes at least 10 to 20 seconds until it moves

While debugging in Flash Builder, the app is sluggish while the

are

loading, but not unresponsive the way I'm seeing using fdb, and 
the

assets
load MUCH more quickly.


Does anyone have any idea here? I'd love to continue trying to

not an option...

Maybe, but execution stopped before it quit.


Could it just be memory?  The fdb files in /bin/ are batch and
shell
scripts

and you can change the VMARGS line and give it more memory and 
see

if
it
gets further.


Worth a shot, but I'm not sure what to change:

VMARGS="-Xmx384m -Dsun.io.useCanonCaches=false "

java $VMARGS $D32 "-Dapplication.home=$FLEX_HOME" -jar
"$FLEX_HOME/lib/fdb.jar" "$@"

Which is the memory setting?

I would not use the IDEs since you can reproduce the issue 
with

command
line

FDB.  In theory, there Eclipse projects files are there in 
Git.

You'll
need

Eclipse 3.6 minimum, load all of the projects in, fix up 
errors,

etc.


Then when you launch a debug config for FDB, you should just 
be

able
to
run

the same steps as if it were off the command line, and if it 
hangs,

pause
Java execution and see where it is.  Or is it the player that
hangs?


I really don't know what hangs. I doubt it's the player, 
because it

works
if
I
debug directly in Flash Builder.

Is command-line FDB no longer responsive?  Can you quit the 
player?

That
might help determine what is hung.


Below is the command line log. Maybe it means more to you than 
to

me...
;-)

There should be a trace for each font that's loaded, but 
there's

only a
trace
for two of them (in this document). That means that the code
execution
was
halted prematurely after a couple of the swfs were loaded.



If there's a newer version of fdb waiting to be donated, I may 
just

hold
off

on this until we have it, because there's a good chance this 
issue

is
fixed
already since things work in Flash Builder...

This donation is probably a couple of months away if you can 
wait

that
long.

Maybe I can find time to find the code and see how different 
it is

from
what
we have.


Flash Builder works. I'd like to try IntelliJ IDEA, but 
there's the

obvious

question of how much time I'd need to invest in that. If it 
means

helping
to

fix fdb, I might do it, but if the work was already done, I 
don't

see
spending
the time just to be able to use a new IDE a few months early.
