Subject: tomcat won't download large files -- out of memory error
I have some large zip files I want to make available for download. When I
try to download a 70MB file, tomcat is trying to cache these huge files
(it seems). The result is that downloading them always fails. I *want*
caching for most everything eg jpegs, html, etc and I've set tomcat to use
up to 1.5GB of memory.
Is there a way to limit the size of the file that will be cached? It's
regrettable that failure to cache a file can't gracefully degrade into
just not caching it.

Lloyd... dont know, its definitely running out of mem, but I'm not sure its
because of a 70 meg file...
The default static cache size is 10 megs, so its doubtful that TC is caching
that file...
We run video content on the Lan and some of that stuff is 700 megs on
standard settings... out of the box settings.
We are still running TC 5.5.25 in production...
I dont know the MAC, but its possible that its just not setting enough
memory...
I guess the MAC has its own TC and its own JRE... so I have no idea how you
monitor stuff, or what the defaults are.
If it does have the later Sun JRE VisualVM tool... thats a nice way to watch
what your TC is doing.
Is it been served by tomcats default servlet or from a custom servlet... if
the later the coder may infact be sticking it all on the heap, very likely
it will break then.
The default servlet in TC is smarter than that...
I dont think a 70 meg file should pose any problems served as a static
file...
I would try another TC version just to make sure... and I would ask
[EMAIL PROTECTED] as well if you dont come right here.
I think you may be seeing a symptom of another problem... ie something else
is consumed all the memory, and the file down load is the straw that broke
the camels back. Maybe another test case is in order where you make a little
webapp with nothing else but the static file in it... if that works, then
something else in that webapp ate your memory...
Good Luck...
