Univention Bugzilla – Bug 37342
Several tdbbackup processes piling up (blocked by samba)
Last modified: 2020-07-03 20:54:49 CEST
In an internal UCS@school environment the Samba server was in an unusable state, blocking S4 LDAP searches: ldap.SERVER_DOWN: {'desc': "Can't contact LDAP server"} There was only one Samba process left, which apparently had refused to die during a samba restart: 4924 ? S 0:01 /usr/sbin/samba -D The issue probably has caused several tdbbackup jobs piling up: 2397 ? Ss 0:04 /usr/sbin/cron 31430 ? S 0:00 \_ /USR/SBIN/CRON 31462 ? Ss 0:00 | \_ /bin/sh -c /usr/sbin/univention-samba4-backup 31470 ? S 0:00 | \_ /bin/bash /usr/sbin/univention-samba4-backup 31531 ? S 0:00 | \_ tdbbackup ./private/sam.ldb.d/DC=NAJJAR,DC=LOCAL.ldb 22854 ? S 0:00 \_ /USR/SBIN/CRON 22892 ? Ss 0:00 | \_ /bin/sh -c /usr/sbin/univention-samba4-backup 22900 ? S 0:00 | \_ /bin/bash /usr/sbin/univention-samba4-backup 22988 ? S 0:00 | \_ tdbbackup ./private/sam.ldb.d/DC=NAJJAR,DC=LOCAL.ldb 17992 ? S 0:00 \_ /USR/SBIN/CRON 18031 ? Ss 0:00 \_ /bin/sh -c /usr/sbin/univention-samba4-backup 18038 ? S 0:00 \_ /bin/bash /usr/sbin/univention-samba4-backup 18105 ? S 0:00 \_ tdbbackup ./private/sam.ldb.d/DC=NAJJAR,DC=LOCAL.ldb Cause and effect are a bit unclear, but judging from the PIDs I would guess that samba is the culprint. Anyway, The tdbbackup processes must not pile up like that.
