All that is needed is for one > more connector_process cycle, but the connector never again appears in the > work list. > There is an optimization in the connector processor that says "if the socket > has accepted all of the current data for send, clear the SEL_WR flag". The > problem is that when the data-for-send is the last data to be sent on the > connection, the connector is never again processed and hangs, using resources > and keeping the socket from fully closing. -- This message was sent by Atlassian JIRA (v6.1#6144)
