Your browse operation is unable to complete in the 60 seconds allowed for gateway RPC calls. You will need to perform this operation in small, non-recursive chunks, and/or run it in a gateway script (to not have the timeout). Browse operations are expensive, so you should save the results somewhere for later callers to re-use.
