[vchkpw] pop3 auth

[Marcos Dutra]

Hi people,

Today again i've got a message "File busy try again later!"  in my kmail when 
i tried log in pop3 server. Well my boss received too this message,  and i 
tried up the value from /proc/sys/fs/file-max to 10240, and the file-nr is 
8192    6285    10240

Verifing the problem, i lookup in the file file_lock.c in the vpopmail source 
end has this code:
int get_read_lock(FILE *fs)
{
 int try = 0;

        while(read_lock(fileno(fs), 0, SEEK_SET, 0) < 0)
        {
                if (errno == EAGAIN || errno == EACCES || errno ==ENOLCK )
                {
                        /* there might be other errors cases in which
                        * you might try again.
                        */
                        if (++try < MAX_TRY_RLOCK) {
                                (void) sleep(2);
                                continue;
                        }
                        (void) fprintf(stderr,"File busy try again later!\n");
                        return(-1);
                }

                return(-2);
        }
        return(0);
}


I see part of code above and this error is caused by what exactly?
I see the file vpopmail.c and it have a function called POP_AUTH_OPEN_RELAY, 
it call a  file_lock if  the cdb generation give a error.

I don't no why this error appears to me, somebody knows?
