[Pkg-openldap-devel] Bug#689025: slapd: chokes on unresponsive syslogd

[Dominik George]

Package: slapd
Version: 2.4.31-1
Severity: important

The slapd process hangs when sending log data to an unresponsive syslogd.

In out site setup, all servers log to a central MySQL database through rsyslog.
rsyslog becomes unresponsive when having too much data queued, which happened when
the line to the log server came down for a loner time period several times last week.
rsyslog then refuses to accept any new logs before commiting all queued messages to
MySQL.

Although this is possibly an rsyslog bug, slapd should not run into a freeze due to
that. It didn't even come back up after syslog functionality had been re-established.
