I'm setting up an HA ftp server (amongst other services).<br><br>When
two connections happen simultaneously, and (more specifically) the same
user from two IP's attempt to access the same file (one for reading, and
one for writing), the processes both hang. And all subsequent attempts
to either read or write the file fail.<br>
<br>The two processes that seem to have caused the lock:<br>user 24139

proftpd: cbs - ::ffff:xxx.yyy.103.208: STOR prim_wo_img_dom.obs<br>
<br>(there are 49 other process trying to do the same things, but these
are the first ones.)<br><br>I'm more than happy to provide any
information needed on this issue:<br><br>OSL<br>CentOS release 5.4
