--- Begin Message ---Package: libnet-server-perl Version: 2.006-1 Severity: grave Hi, I have a starman application that regularly dies under load with a backtrace like: Message: Can't use string ("") as a subroutine ref while "strict refs" in use at /usr/share/perl5/Net/Server/SIG.pm line 72, <$read> line 2002. at /usr/share/perl5/Net/Server/SIG.pm line 72 Net::Server::SIG::check_sigs() called at /usr/share/perl5/Net/Server/PreForkSimple.pm line 337 Net::Server::PreForkSimple::close_children('Starman::Server=HASH(0x84e7a8)') called at /usr/share/perl5/Net/Server.pm line 735 Net::Server::server_close('Starman::Server=HASH(0x84e7a8)') called at /usr/share/perl5/Starman/Server.pm line 124 (...) Some debugging shows that the problem is that several Net::Server modules (e.g. Net::Server::PreforkSimple) tries to trap signals with Net::Server::SIG using “CHLD” as the signal name. Net::Server::SIG in turn adds a signal handler like this: $SIG{$sig} = sub{ $Net::Server::SIG::_SIG{$_[0]} = 1; }; However, when that sub is called, it is called with “CLD” as signal, not “CHLD” (seemingly Perl has two names for this). This in turn confuses check_sigs, which wants to do this with $sig set to “CLD”: $_SIG_SUB{$sig}->($sig); whereupon the crash happens. I think the smallest fix around this is something like $sig = 'CLD' if ($sig eq 'CHLD'); in the top of register_sig(), but I might be mistaken. In any case, this makes Net::Server::PreforkSimple, and probably several others, rather unusable, since they may crash at almost any time, and there is no simple workaround that I can see. (Thus the RC severity.) -- System Information: Debian Release: 7.0 APT prefers stable APT policy: (750, 'stable') Architecture: amd64 (x86_64) Kernel: Linux 3.9.0+sesse01 (SMP w/16 CPU cores) Locale: LANG=en_DK.UTF-8, LC_CTYPE=en_DK.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Versions of packages libnet-server-perl depends on: ii libio-multiplex-perl 1.13-1 ii libio-socket-inet6-perl 2.69-2 ii libnet-cidr-perl 0.15-1 ii libsocket6-perl 0.23-1+b2 ii perl 5.14.2-21 libnet-server-perl recommends no packages.
