I'm trying to speed up my pipeline execution using Parallel Chunk Start/End nodes. Between them I put FileConverter followed by FeatureFinderMetabo among other nodes that are less significant in my case. The issue is that I get the following error in log from time to time:
"ERROR FileConverter 0:255:280:295:277 Execute failed: ("ConcurrentModificationException"): null
ERROR Parallel Chunk End 0:255:19 Execute failed: Not all chunks finished - check individual chunk branches for details."
and the execution stops. It happens, in particular, when I pass many files to the workflow and Parallel Chunk Start uses up to 8 chunks. Any ideas how to avoid this? I can share this problematic part of the workflow if necessary.
