sramazzina opened a new issue, #3056: URL: https://github.com/apache/hop/issues/3056
### Apache Hop version? 2.5.0 and any previous version ### Java version? openjdk-11 ### Operating system Linux ### What happened? We are experiencina a NullPointerException on pipelines where we have transforms that receives as input more two flows. Let me summarize below some of the point that could be interesting for our investigation: - The problem always happen when we have two flows as input of a transform. - The problem always happen at the very beginning of the processRow method and is always related to code where the `getInputRow()` method is involved in a complex inline instruction (like `data.fieldnrs[i] = getInputRowMeta().indexOfValue(meta.getFieldName()[i]);` or `data.outputRowMeta = getInputRowMeta().clone();`) and that method returns null - The problem randomly happens 2 or 3 times (lastly it is this way) per day sometimes or nothing at all for a long time then it apperas again The fact that is a random problem makes it hard to reproduce and for this reason till now we were unable to catch it. We asked the customer some context data and we got the confirmation that the overall load of the server at the time of the issue is normal. The system isn't under severe stress I post here some screenshots of the pipeline by putting in evidence the transforms that gives the issue    ### Issue Priority Priority: 1 ### Issue Component Component: Transforms -- This is an automated message from the Apache Git Service.
