What exactly did the new forking code do for us anyway?

[Matt Doherty]

What exactly did the new forking code do anyway? Sorry, Im not a programmer.
Wish I was,..
I will keep version 3.29.8!! for now. Because in RedHat 7.2
Mailscanner/Spamassassin are working very nicely !!!

  I have had a couple of instability problems reported to me, involving the
  new forking code I released in 3.22-8. It works fine on most systems, but
  can cause MailScanner to silently die on a few systems, notably some
  Solaris versions.

  I have therefore backed out the new forking code, hence the release of
3.22-9.

  If you don't want to upgrade but are happy applying simple patches, then
  edit /usr/local/MailScanner/bin/mailscanner or
  /opt/mailscanner/bin/mailscanner (depending on where you have it
installed)
  and apply this:

  106,119c106,119
  < #fork && exit;
  < #setsid();
  < $SIG{CHLD} = \&REAPER;
  < if (fork) {
  < wait; # Ensure child has exited
  < exit 0;
  < }
  < # This new child's parent is perl
  < # Close output streams to break connection to handin server
  < close(STDIN);
  < close(STDOUT);
  < close(STDERR);
  < fork && exit 0;
  < # This new grand-child's parent is init
  ---
  > fork && exit;
  > setsid();
  > #$SIG{CHLD} = \&REAPER;
  > #if (fork) {
  > # wait; # Ensure child has exited
  > # exit 0;
  > #}
  > ## This new child's parent is perl
  > ## Close output streams to break connection to handin server
  > #close(STDIN);
  > #close(STDOUT);
  > #close(STDERR);
  > #fork && exit 0;
  > ## This new grand-child's parent is init

  i.e. un-comment the first 2 lines and comment out the others.

  I'm really sorry about this folks :-(

  Isn't it a good thing most people are on holiday...

  You can of course download 3.22-9 from the usual location:
