CostlyOstrich36 Fixed: It was a cache issue in NFS. However, we discovered an important detail—there were two folders in the cache: datasets and global . When we started the ClearML script, it began indexing the entire global folder, which was the reason the script got stuck. After mounting only the datasets folder, there was no delay anymore.
Do you know how to disable indexing? If we mount the global folder on all instances, it grows very fast, and each time a new task indexes additional results.
