CloseWellKnownConnections() closes all connections and deallocates
|
||
|
|
their data. Thus all entries in ListenTransConns are invalid.
|
||
|
|
To avoid access to those entries set ListenTransCount to 0.
|
||
|
|
This avoids crashes when CloseWellKnownConnections() is called twice
|
||
|
|
for instance when FatalError() is called on Xserver shutdown.
