Gas errors on the network

A number of subgraphs on the network have hit the default gas limit, so indexers must configure a larger one. We should look into these with the purpose of adjusting gas costs that may be overestimated. These subgraphs have been reported as going over the limit:

The Eden Network (QmWd8mE5nedM5smvzQhDYmsWEcgiAtdqccdZ2XCsvCdVEK, source link case has more details. It fails with:

Probably due to iterating over a large collection, the network.stakers array might be as large as 4.5k entries.

Start with the gas-limit failure in the reported log and compare it with the Eden Network source at packages/subgraph/src/network.ts lines 116-124, especially the large network.stakers collection. Trace how this execution is metered in graph-node and identify whether the reported gas cost is overestimated; done means the affected subgraphs no longer hit the default limit without requiring a configuration increase.
