SIOWriter couldn't write event header [message #2236] Wed, 01 August 2012 09:50

Dear all,

Trying to run 2 processors in Marlin, the second one being LCIOOutputProcessor, I got a crash at the first event with the following message :

A runtime error occured - (uncaught exception):
lcio::IOException: [SIOWriter::writeEvent] couldn't write event header to stream: _scratch_RawHits_slcio0
Marlin will have to be terminated, sorry.

How could I debug such a thing ? Is there a way to tell SIO to be more informative ?
Is it a usual message if I've not set properly something ?

In case you want to try to reproduce it :
I'm using ilcsoft release v01-14,
I'm running processors from the Trivent package release 8 ( svn co Trivent )
Look into the README file for instructions on how to compile the package.
I'm using the Marlin xml file which is under <Trivent>/steer/streamout.xml where I've uncommented the LCIOOutputProcessor.
The input file I'm using is on the calice grid at /grid/calice/SDHCAL/TB/CERN/PS_April2012/RAW/DHCAL_713775_I0 _0.slcio

Thanks for any advices.
