Using Connectivity Mod's Debugging Tools to Track Down a Problematic Mod

When a server or client misbehaves and you do not know which mod is responsible, the Connectivity Mod's debugging tools narrow it down by watching the network layer.

Turn on advanced logging

Enable the mod's advanced error logging and packet logging before you reproduce the problem. These features record detailed information about packets, including ones that are too large and their source. The more detail you capture, the easier the culprit is to spot.

Reproduce the issue in a controlled way

Join the server or load the world, then perform the action that triggers the problem — opening a specific container, using a machine, or entering a chunk. Immediately after, stop and read the log. Look for the last packets logged before the failure; the mod that sent them is your suspect.

Cross-check with packet stats

Run /connectivity packetsClient to see outgoing traffic counts. If one packet type dominates right when the problem occurs, that confirms the suspect. On the server side, use the server stats command to see whether the same pattern appears in incoming traffic.

Act on the finding

Once you have a suspect mod, test by removing or updating only that mod. If the problem disappears, you have your answer. The Connectivity Mod does not fix other mods, but it tells you where to look.
