Previous Allocation not found

sentry-io opened this issue · comments

From time to time, we see an issue in Sentry about a previous allocation not being found. For example, this could happen when the event stream gets disconnected. Therefore, in this case we want to filter those events that have a timestamp before the disconnect, ideally preventing this issue from occurring.

Before starting with this issue, confirm this assumption first.

Currently, we see this issue regularly on production, where it occurs mostly during the nights (indicating that our unattended-upgrades are causing the issue).
