[vchkpw] POP authentication error

[matiaslambert]

Hi,
I use vpopmail in a Debian server.
I have no problem until yesterday night when I recompile vpopmail for log 
all authentications.
My configuration string is
./configure --enable-defaultquota=50000000S,500C --enable-popuser=vpopmail 
--enable-tcpserver-file=/etc/tcp.smtp --enable-clear-passwd=y 
--enable-vpopgroup=vchkpw --enable-roaming-users=y --enable-logging=y
UID for vpopmail user is 1009
GID for vchkpw group is 1001
( that was working ok until yesterday ) 

Now when some user authenticate pop some vchkcw process never go down.
And then all users are rejected with the this error: File busy try again 
later!
I check it with strace and it say that:
strace -p 3128
wait4(-1, 0xbffffcb8, 0, NULL)          = -1 ECHILD (No child processes)
wait4(-1, 0xbffffcb8, 0, NULL)          = -1 ECHILD (No child processes)
wait4(-1, 0xbffffcb8, 0, NULL)          = -1 ECHILD (No child processes)
wait4(-1, 0xbffffcb8, 0, NULL)          = -1 ECHILD (No child processes)
wait4(-1, 0xbffffcb8, 0, NULL)          = -1 ECHILD (No child processes)
wait4(-1, 0xbffffcb8, 0, NULL)          = -1 ECHILD (No child processes)
wait4(-1, 0xbffffcb8, 0, NULL)          = -1 ECHILD (No child processes)
wait4(-1, 0xbffffcb8, 0, NULL)          = -1 ECHILD (No child processes)
wait4(-1, 0xbffffcb8, 0, NULL)          = -1 ECHILD (No child processes) 

When clearopensnmp start it have the same problem ( the same trace too ).
And it have an error in the UID and GUI of open-smtp ( it was ok after 
install the software ).
