I beleive, u are concerned about Virtual Circuit Latch contention, which appears as "virtual circuits " wait event and v$session_wait.

when numerous connections are lost and being re-established within a small window of time, in this
case one should find out the reason why dispatchers lost connections. Contention can also be caused by a blocked listener, a number of sessions then appear to abort or timeout. Restarting the listener clears the problem in most of the cases.
