It was put into the code in order to track down problems with applications
that are closing all of the 'unused' file descriptors when they do
and execve( lpr ), or do not close file descriptors.
And it looks like we have a couple of culprits right here: ghostview and Acrobat
Reader.
This surfaced on a couple of systems when lpr got an 'out of file descriptor'
system level error... Needless to say, I was perturbed.
The 'Max_open()' code was put in to try and find out just how many file
descriptors were in use. I would use it to track the 'high water mark'
and the when I did an EXECVE I would close only the ones 'below'
the high water mark.
Here is the code:
void Max_open( int fd )
{
if( fd > 0 ){
if( fd > Max_fd+10 ){
FATAL(LOG_ERR) "Max_open: fd %d and old Max_fd %d", fd, Max_fd);
}
if( fd > Max_fd ) Max_fd = fd;
}
}
All you need to do is comment out the check...
void Max_open( int fd )
{
if( fd > 0 ){
#if 0
if( fd > Max_fd+10 ){
FATAL(LOG_ERR) "Max_open: fd %d and old Max_fd %d", fd, Max_fd);
}
#endif
if( fd > Max_fd ) Max_fd = fd;
}
}
But you might also send a flame to the ghostview and Acrobat folks...
