android - Files do not download completely or get corrupted -

-

i have android app downloads files tomcat7 running on redhat linux server needed. server under control , authorized users can download. files database information , can quite large, as 4.8mb. however, tiny files fail download fully.

these files have downloaded fine in past, started fail download completely. don't know if problem on server or client side yet. server bandwidth usage ~10%.

i looking guidance on how determine if it's server problem, or problem in android app. have searched hours trying find may related without success.

i don't know if it's related, securecopy (scp) stalls frequency on server.
