FTP daemon stops responding

I have a strange problem with the FTP server on AIX 5.2. During the busiest time of the day, we get intermittent connection failures or timeouts connecting to the ftp server. The only thing clue that I can find is that daemon log shows the following message:

ftpd[52222]: /bin/ls: Resource temporarily unavailable

Has anyone ever seen this error? Is there anything else that I can look at that might help diagnose this issue?

Thanks in advance for you help!

FTPUSERS(5)						     Linux Programmer's Manual						       FTPUSERS(5)

NAME

       ftpusers - list of users that may not log in via the FTP daemon

DESCRIPTION

       The  text  file	ftpusers  contains a list of users that may not log in using the File Transfer Protocol (FTP) server daemon.  This file is
       used not merely for system administration purposes but for improving security within a TCP/IP networked	environment.   It  will  typically
       contain	a  list  of  the  users that either have no business using ftp or have too many privileges to be allowed to log in through the FTP
       server daemon.  Such users usually include root, daemon, bin, uucp, and news.  If your FTP server daemon doesn't use ftpusers  then  it	is
       suggested  that	you  read  its	documentation  to find out how to block access for certain users.  Washington University FTP server Daemon
       (wuftpd) and Professional FTP Daemon (proftpd) are known to make use of ftpusers.

   Format
       The format of ftpusers is very simple.  There is one account name (or username) per line.  Lines starting with a # are ignored.

FILES

       /etc/ftpusers
