I faced with that issue on 11.2.0.4 version on Linux 6. There were no messages or warnings in the alert log file.
Export status showed as executing and there weren’t any errors.
I used below sql to identify wait:
select v.status, v.sid,v.serial#,io.block_changes,event from v$sess_io io, v$session v where io.sid = v.sid and v.saddr in ( select saddr from dba_datapump_sessions ) order by sid;
