Error description
Agent with the name "AGENT_Y" was transfering files without problems, but later on, the agent process was still running but no new transfers involving this agent could be started. The agent appeared not to read from its command queue "SYSTEM.FTE.COMMAND.AGENT_Y". The agent also did not respond to the commands "fteStopAgent AGENT_Y" nor "fteStopAgent -i AGENT_Y" . There was 1 error message date:time 0027 Receiver File state: Index: 0, Filename: TransferMode:BINARY TransferType:FILENAME TransferName:/opt/home/xxxxxx03/WMQFTE/inbox/mqmpkg.COPIED3 Attributes:GEXIST=ERROR GCHECKSUMMETHOD=MD5 GDISPOSITION=LEAVE, Position: 0 ], auditInformationSetArray: ■com.ibm.wmqfte.statestore.impl.FTEAuditInformationSet@17e2eb9 super.toString(): Common State . It appears that an fteCancelTransfer command was made to cancel a given transfer. This was sent to the source agent which in turn sent an internal cancel message to the destination agent AGENT_Y. This internal cancel message then resulted in the command thread sending a cancel message to the receiving transfer thread. The command thread is then waiting for the receieving thread to end. However the receiving thread appears to have hung which in turn is causing the command thread to hang. However it was found that there was another transfer that was also writing to the same file. This transfer also appears to be hung and not progressing. Therefore it is possible that there is a locking problem between the 2 transfers.
Local fix
