In the last 4/5 days I cannot get my refinement jobs done on haddock 2.4. I can see each job going through the it0, it1 and itw and reaching the 100%, then they freeze and the job status becomes: unknown. I am using structures which I used before on haddock and suggested clustering parameters so I cannot explain why this is happening.
It looks like you are running a full analysis rather than only clustering and since this is a large system it takes a long time even after all models have been generated.
