Deallocate/Release channel failed (urgent)

Question

Hello forum users,
I encountered a serious issue with RMAN.
I use an RMAN script, allocate manually 5 channels for backup to an external server with Legato/LTO.
In RMAN log backup finishes successfully but RMAN process do not release channels and for next backup RMAN returns errors because it considers that there is a running backup.
Did someone encounterer this issue ? What can I do ?
Regards,
Guillaume

Hi Alan,
Application "EMC Networker" is used to launch rman script :
NSR.log (EMC Networker)
cmd_args = send "'NSR_ENV=(NSR_GROUP=Archive_MYINSTANCE,NSR_SERVER=server.localdomain,NSR_SAVESET_NAME=d:\nsr\rman_scripts\archive_all_myinstance.txt)'"
rman_script = d:\nsr\rman_scripts\archive_all_myi.txt
saveset_name = d:\nsr\rman_scripts\archive_all_bip.txt
