hi,

  in 17.0.6.2 i am trying to run (re)reconstruction in heavy ion mode from pp esds. in this case i am getting a failure in writing convertedmuidcbtracks to output stream, which prevents from getting any usefull output. the error is the following:
storegatesvc                                      warning  setupproxy:: error setting up proxy for key convertedmuidcbtracks and clid 117682415

   i am running the following transform:

  input file available at /eos/atlas/user/o/olszewsk/esd.348881._000002.pool.root.1

  can you tell is this fixable in the transform or is this a problem with muon reconstruction?

  cheers, andrzej
