User response
Use the SYNC_SEND or SYNC_SEND_RECEIVE interaction
on a shareable persistent socket connection. If your intent is to
execute a SYNC_END_CONVERSATION, SYNC_RECEIVE_ASYNCOUTPUT_SINGLE_NOWAIT,
or SYNC_RECEIVE_ASYNCOUTPUT_SINGLE_WAIT interaction, do not specify
a value of true for the ignorePURGCall property.
