SYMPTOMS
The Explain details for the Server object, Sessions Errored Out counter in
Performance Monitor, reads as follows:
The number of sessions that have been closed due to unexpected error
conditions. Indicates how frequently network problems are causing
dropped sessions on the server.
This explanation fails to mention that this counter also increments when
normal session disconnects occur as a result of the AUTODISCONNECT
parameter. The AUTODISCONNECT value represents the number of minutes that
idle sessions have before being disconnected automatically by a server.
The default value is 15 minutes. This counter increments as a result of
normal server operation, not as an indication of network problems. When
this counter increments as the result of network problems, other symptoms
occur, which may indicate a problem exists. If network users connected to
the server remain unaffected when this counter increments, then automatic
disconnections and reconnections occur normally. Therefore, this behavior
is considered an expected condition, not an unexpected error condition as
the Explain button currently reads.
