samba - May 2013 - [samba4] "rlimit_max: increasing rlimit_max (1024) to minimum Windows limit (16384)" message with smbstatus command

Hello,

I'm using samba4 (4.0.5 version) in Debian Wheezy. When I run the
"smbstatus" command, I have a curious message. Here is an example:

#----------------------------------------
root at samba-1:~# smbstatus -b
rlimit_max: increasing rlimit_max (1024) to minimum Windows limit (16384)

Samba version 4.0.5
PID     Username      Group         Machine

# etc.

1) What is the meaning of the message below?

2) Is it a serious problem?

Thanks in advance for your help.
