I have four hosts all running 11.3-RELEASE-p5 on the same subnet. Yesterday I did the usual "freebsd-update fetch && freebsd-update install" on all four. They came back up fine but about 4 hours later one of them started reporting problems with ldap search. I poked at it a bit but it was struggling to do anything so I had to reboot it. It came back up clean but the problem resurfaced early this morning. from /var/log/messages: Dec 27 03:30:00 [redacted] root: 3:30AM up 11:16, 1 user, load averages: 0.04, 0.07, 0.08 Dec 27 03:35:00 [redacted] root: 3:35AM up 11:21, 1 user, load averages: 0.21, 0.23, 0.15 Dec 27 03:35:10 [redacted] chgrp: nss_ldap: could not search LDAP server - Server is unavailable Dec 27 03:35:12 [redacted] top: nss_ldap: could not search LDAP server - Server is unavailable Dec 27 03:35:35 [redacted] nrpe[76163]: nss_ldap: could not search LDAP server - Server is unavailable Both times I observed this: : ldapsearch -v -LLL -x -h [redacted].ee.washington.edu -b dc=ee,dc=washington,dc=edu uid=[redacted] ldap_initialize( ldap://[redacted].ee.washington.edu ) ldap_sasl_bind(SIMPLE): Can't contact LDAP server (-1) The other hosts on the same subnet have no such problems. I re-ran fetch & update but it said there was nothing to do. Any hints where I should start poking this? thanks, nomad
