Description

Dear ColabFold team,

I am running a Boltz2 pipeline that relies on the ColabFold MSA server. For a subset of input sequences (provided via a .txt file), the MSA requests remain indefinitely in the PENDING state and do not progress to RUNNING or completion.

Other 90% sequences that I worked with have been processed successfully, but the affected ones consistently stall even after repeated attempts. I have also retried multiple times with pauses between submissions, but the issue persists.

Could you please advise whether this is a known issue or if there are recommended ways to handle such stalled requests?

Research direction

Start with the attached failed_sequences.txt and reproduce the ColabFold MSA server requests for those sequences, comparing them with the 90% that completed successfully. Investigate why the affected requests remain PENDING rather than reaching RUNNING or completion; done means identifying a reproducible cause or documented handling for the stalled requests.
