2012-12-03 13:23:44 Mattias Andersson description I'm running 64-bit Ubuntu Desktop 12.04.1, with kernel version 3.2.0-32-generic. I have configured LDAP PAM authentication for several clients and this problem is reproducible on each client system. If I'm not running the name service cache daemon (nscd), I'm getting the following errors when I attempt to start either 'acroread' or 'thunderbird': (acroread:11520): GLib-WARNING **: getpwuid_r(): failed due to unknown user id (537) (thunderbird:11298): GLib-WARNING **: getpwuid_r(): failed due to: Connection refused. The solution so far has been to always keep the nscd service running. However, after a recent update, nscd is now crashing each time it is started. Here is the output when running "strace nscd -d -d -d": getrlimit(RLIMIT_NOFILE, {rlim_cur=1024, rlim_max=4*1024}) = 0 epoll_create(100) = 13 epoll_ctl(13, EPOLL_CTL_ADD, 12, {EPOLLRDNORM, {u32=12, u64=12}}) = 0 epoll_ctl(13, EPOLL_CTL_ADD, 3, {EPOLLRDNORM, {u32=3, u64=3}}) = 0 epoll_wait(13, Mon 03 Dec 2012 02:02:00 PM CET - 11145: pruning passwd cache; time 1354539720 Mon 03 Dec 2012 02:02:00 PM CET - 11145: considering GETPWBYUID entry "0", timeout 1354538746 Mon 03 Dec 2012 02:02:00 PM CET - 11145: considering GETPWBYUID entry "0", timeout 1354510222 Mon 03 Dec 2012 02:02:00 PM CET - 11145: considering GETPWBYUID entry "0", timeout 1354280394 Mon 03 Dec 2012 02:02:00 PM CET - 11145: considering GETPWBYUID entry "1000000", timeout 1354279029 Mon 03 Dec 2012 02:02:00 PM CET - 11145: considering GETPWBYUID entry "120", timeout 1354274881 Mon 03 Dec 2012 02:02:00 PM CET - 11145: considering GETPWBYNAME entry "www-data", timeout 1354280394 Mon 03 Dec 2012 02:02:00 PM CET - 11145: considering GETPWBYNAME entry "perot", timeout 1354538746 Mon 03 Dec 2012 02:02:00 PM CET - 11145: Reloading "perot" in password cache!
