Issue
Sessions in Posit Cloud may unexpectedly disconnect or timeout even during active use, particularly when running memory-intensive operations. This can appear as a timeout issue but may actually be related to resource limits.
Description
When running resource-intensive operations in Posit Cloud, you may observe:
- The Stop sign icon begins flashing.
- A green icon appears with the message "session suspended child process running."
- The session disconnects shortly after.
- These issues may occur even when the RAM usage indicator appears to be in the green zone.
Solution
To resolve these issues:
Immediate Workarounds
- Run intensive operations as background jobs to allow the UI to detach more cleanly.
- Save intermediate results before running resource-intensive operations (e.g., using saveRDS()).
- Break down large operations into smaller chunks.
Long-term Solutions
- Check your current project resources under Project Settings.
- Consider upgrading your plan if you consistently need more resources.
- Monitor memory usage during operations using the RAM gauge at the top of the UI.
- Optimize your code to reduce memory usage where possible.
Additional Tips
- Clear your R environment regularly to free up memory.
- Use memory-efficient data structures and operations when possible.
- Consider using data.table or other memory-efficient packages for large datasets.
