storescp Association Aborted

[PMarcheschi]

Hi

I'm trying, under linux dcmtk-3.6.4, to create a script in order to move to an external server, zipped studies.
But I have an error with storescp: I: Association Aborted
I use dcm4chee server to send dicom files, If I use dcm4che storescp, I receive files normally without error.

I read the https://forum.dcmtk.org/viewtopic.php?t=3722 , but I need to recompile the tool.
I tried to recompile the tool with gcc 5.4.0 issuing the make with:

Code: Select all

make -j8 CFLAGS=-DDISABLE_RECV_TIMEOUT

It compiles fine but I got the same error.

this is the command line I use:

Code: Select all

~/bin/dcmtk/bin/storescp -v +v +xa -sp -pm -dhl -od ./BIGDATA  -xcs "./bin/comprimi.sh #p&"  2100

On the dcm4chee server I got a message:

Code: Select all

failed with status A702 Error Comment:null
  Started at 2019-10-28 18.00.19,780 failed at 2019-10-28 18.00.29,804

on storescp side , I got:

Do you have some tip to solve the issue?

Thank you

From config/docs/macros.txt (DCMTK 3.6.4):

Code: Select all

DISABLE_RECV_TIMEOUT
  This macro is not supported anymore since the timeout for the recv() function
  is now configurable at runtime.  See global variable dcmSocketReceiveTimeout.

The socket timeout is now configurable for various DCMTK network tools, e.g. storescp:

Code: Select all

 other network options:
    [...]
    -ts   --socket-timeout       [s]econds: integer (default: 60)
                                 timeout for network socket (0 for none)

You should enable the --debug output of the storescp to get more details in the log.

Hi
Thank you for clarifying that.
I tried a lot of combination with no luck.

I discovered that I can receive all images with --fork option.
But this option is incompatible with the --exec-on-eostudy command.
error: --exec-on-eostudy not allowed with --fork

Maybe I have to act on the dcm4chee server side.

Yes, it sounds like the Storage SCU (dcm2chee) is starting multiple associations on the same port. This is only supported if storescp is started in "fork mode".
