Table 5-3 Common connection codes
DescriptionConnection
code
Client aborts the connection.A1
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.
B1
BER tag is longer than the nsslapd-maxbersize attribute value. For further information about
this configuration attribute, see “nsslapd-maxbersize (Maximum message size)”.
B2
Corrupt BER tag encountered.B3
Server failed to flush data response back to client.B4
Closed or corrupt connection has been detected.P2
Client does not receive a result within the specified idletimeout period. For further information
about this configuration attribute, see “nsslapd-idletimeout (Default idle timeout)”.
T1
Server closed connection after ioblocktimeout period was exceeded. For further information
about this configuration attribute, see “nsslapd-ioblocktimeout (IO block time out)”.
T2
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.
5.2.1 Error log logging levels
The error log can record different amounts of detail for operations, as well as different kinds of
information depending on the type of error logging enabled.
The logging level is set in the nsslapd-errorlog-level configuration attribute. The default log level
is 16384, which included critical error messages and standard logged messages, like LDAP
results codes and startup messages. As with access logging, error logging levels are additive. To
enable both replication logging (8192) and plug-in logging (65536), set the log level to 73728
(8192 + 65536).
NOTE:
Enabling high levels of debug logging can significantly erode server performance. Debug log
levels, such as replication (8192) should only be enabled for troubleshooting, not for daily
operations.
