Subject:

Test suite freezes: Unable to listen on port 10636: Address already in use

This is blocking the installation of the module, which is blocking the testing of a fix for another module [https://rt.cpan.org/Ticket/Display.html?id=83900] This has happened every time I've tried to install the module: Show quoted text

This has been a consistent but un-repeatable issue since the initial release of this module and there are several workarounds but no fix. What OS/platform are you using? Are you using any iptables-like firewall? Does fork() work otherwise normally for you in this environment?

I'm using: ➔ cat /etc/redhat-release CentOS release 5.8 (Final) ➔ uname -a Linux fulcrum-chz.dave.net-a-porter.com 2.6.18-308.24.1.el5 #1 SMP Tue Dec 4 17:43:34 EST 2012 x86_64 x86_64 x86_64 GNU/Linux I believe our jenkins build server is Centos5 too. fork() has never shown any signs of misbehaving. We rely on it moderately heavily for daemons for our apps. There are some iptables rules on the box, but they're all listed as ACCEPT no DROP or REJECT rules in the output from 'iptables --list'

Ok, I have the same OS in front of me, with no problems. What Perl version?

Nevermind, I see Perl 5.014002 in the test output.

I have added a diagnostic warning and upped the kill signal in https://github.com/karpet/net-ldap-server- test/commit/e3f8e52b93e5a0341e0d12ec86ce463a93e90ed8 please check that out. Even if it does not fix the issue I would like to see the output.

thanks for the quick test. I just pushed some more diagnostics to github. Please git pull and try again.

This one passed (I just did a git pull); there's a slight pause - presumably because of the new 'tried loop'. I've run it a few times with no failure.
