Description:
------------
I'm not able to transfer file bigger 80KB using ssh2_scp_send.
Files smaller 80KB work as expected.

net-libs/libssh2 version 1.4.2
dev-php/pecl-ssh2 version 0.11.3-r1
php dev-lang/php version 5.3.15
also tested with dev-lang/php version 5.4.6 same effects here

php compiled with following use-flags

apache2 berkdb bzip2 cli crypt ctype curl fileinfo filter ftp gdbm hash iconv ipv6 json mysql mysqli nls pcntl pdo phar posix readline session simplexml ssl threads tokenizer unicode xml zlib



Test script:
---------------
ssh2_scp_send($conn_ssh, $local_file, $remote_file, 0666)

Expected result:
----------------
I expect the file to be transfered

Actual result:
--------------
PHP Warning:  ssh2_scp_send(): Failed copying file ...

File is transfered until size of about 80KB is reached then process breaks.

Are there any limits which have to be configured?
