Subject: slapd: slapcat output truncated every now and then
Date: Tue, 15 May 2012 18:33:57 +0200
Package: slapd
Severity: grave
Version: 2.4.23-7.2
Justification: Causes data loss
Every now and then slapcat's output does not contain the whole content
of the LDAP but is truncated at some LDIF entry border (i.e. all printed
LDIF records seem complete).
To reproduce run "while sleep 1; do slapcat | wc; done" on a moderately
busy LDAP server (writes every few seconds to minutes; about 10000
entries) while slapd is running and notice the occasionally occurring
huge change in wc's printed values, e.g.:
# while sleep 1; do slapcat | wc; done
