Regards, Hans -------- Forwarded Message -------- Subject: Aitofs: spurious (?) jog messages and zombies from automountd Date: Wed, 24 Sep 2014 09:10:05 +0200 From: Hans Ottevanger To: freebsd-stable@FreeBSD.org Hi, When accessing a directory for the first time on /net, automounted using the new autofs, I reproducibly get error messages in the log. I have exported a single directory (read/write) from my test server: $ showmount -e soekris Exports list on soekris: /home My client runs 10-STABLE, also known as 10.1-BETA2 these days, updated to r272021. The kernel config is GENERIC minus devices that I do not have, with AUTOFS added. When accessing the server for the first time using: ls /net/soekris/home/hans I get the expected directory listing but immediately also see the following in /var/log/messages: Sep 24 07:39:09 beastie automountd[1554]: child process 2096 terminated with exit status 1 Sep 24 07:39:09 beastie automountd[1554]: child process 2101 terminated with exit status 1 Additionally, a zombie process keep hanging forever: $ pstree 1554 -+= 01554 root /usr/sbin/automountd \--- 02106 root When I wait until the directory is autounmounted and retry the access, the zombie disappears (apparently finally waited for) and I get two others in return: $ pstree 1554 -+= 01554 root /usr/sbin/automountd |--- 02658 root \--- 02663 root and a few extra log messages: Sep 24 08:52:17 beastie automountd[1554]: child process 2106 terminated with exit status 1 Sep 24 08:52:17 beastie automountd[1554]: child process 2653 terminated with exit status 1 Is anyone else seeing this? Do I miss something? Is this expected behavior?
