Hello. Found very strange situation.

My system

code for sending file
========

        $postdata = array(
            'fileid' => $fileid,
            'current_slice' => self::$_current_slice,
            'current_chunk' => self::$_current_chunk,
            'stream' => $stream,
            'controller' => 'node',
            'ctime'    => $ctime,
            'action' => 'upload',
            'password' => Config::get('PASSWORD'),
            'file' => "@".$upload
        );

$ch = curl_init();

            curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, Config::get('connect_curl_timeout'));
            curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
            curl_setopt($ch, CURLOPT_USERAGENT, "Mozilla/4.0 (compatible;)");
            curl_setopt($ch, CURLOPT_URL, $URL.'/index.php');
            curl_setopt($ch, CURLOPT_PORT, Config::get('NODES_PORT'));
            curl_setopt($ch, CURLOPT_POST, true);
            curl_setopt($ch, CURLOPT_POSTFIELDS, $postdata);

=============

so, sending 2000 files into system, it is about 2000*3 *2/3 = 4000 times of execution code above(sending chunk of file to remote server)
and alltime it is about 5-15 erros
like these

errcode=26 errmsg=couldn't open file "Ё”e¦@cОў3„d"

PS - filename is different for different php processes.
====
extra doings

1)if error will appear, retry yet 3 times the same.  - Result - the same error with the same filename "Ё”e¦@cОў3„d"

2)if error will appear, retry the same but without file - means sending just array of data via HTTP POST - Result - the same error with the same filename

3)use CURLOPT_VERBOSE

result:(log of the php process, other processes has others logs)
* About to connect() to t3.host.com port 80 (#0)
*   Trying 204.45.182.26... * connected
* couldn't open file "ЇSGЧ^–8оЪЪЫбнМ"

* Connection #0 to host t3.host.com left intact
* Closing connection #0
* About to connect() to t3.host.com port 80 (#0)
*   Trying 204.45.182.26... * connected
* couldn't open file "ЇSGЧ^–8оЪЪЫбнМ"

* Connection #0 to host t3.host.com left intact
* Closing connection #0
* About to connect() to t2.host.com port 80 (#0)
*   Trying 50.7.10.98... * connected
* couldn't open file "ЇSGЧ^–8оЪЪЫбнМ"

* Connection #0 to host t2.host.com left intact
* Closing connection #0

ps other processes with error, has the same log file, exclude file name, other  not-readable-filename

-- 
4) if error will appear, try to get some file from remote node (useing HTTP GET) - it works, but any POST request doesn't works.
PS
according logs, I am sure, there are the situation, when php process has good sent the first chunk of the user file, but on the second one has error, and then for these php process it is impossible to send request via HTTP POST.
Please, help me, what's up!? 
how can I fix it, how can I understand - what file is it like "ЇSGЧ^–8оЪЪЫбнМ"
