5.1.4. Common Connection Codes
A connection code is a code that is added to the
closed
log message to provide additional
information related to the connection closure.
Connection Code
Description
A1
Client aborts the connection.
B1
Corrupt BER tag encountered. If BER tags,
which encapsulate data being sent over the
wire, are corrupt when they are received, a B1
connection code is logged to the access log.
BER tags can be corrupted due to physical layer
network problems or bad LDAP client operations,
such as an LDAP client aborting before receiving
all request results.
B2
BER tag is longer than the
nsslapd-
maxbersize
attribute value. For further
information about this configuration attribute,
see
Section 2.3.1.76, “nsslapd-maxbersize
(Maximum Message Size)”
.
B3
Corrupt BER tag encountered.
B4
Server failed to flush data response back to
client.
P2
Closed or corrupt connection has been detected.
T1
Client does not receive a result within the
specified
idletimeout
period. For further
information about this configuration attribute, see
Section 2.3.1.60, “nsslapd-idletimeout (Default
Idle Timeout)”
.
T2
Server closed connection after
ioblocktimeout
period was exceeded. For
further information about this configuration
attribute, see
Section 2.3.1.62, “nsslapd-
ioblocktimeout (IO Block Time Out)”
.
U1
Connection closed by server after client sends an
unbind request. The server will always close the
connection when it sees an unbind request.

5.2. Error Log Reference
The Directory Server error log records messages for Directory Server transactions and operations.
These may be error messages for failed operations, but it also contains general information about the
processes of Directory Server and LDAP tasks, such as server startup messages, logins and searches
of the directory, and connection information.
