Repeated out-of-memory crash during a long interactive session in 1.0.109 #5435
Description
Description
Copilot CLI crashed again with an out-of-memory condition during a long interactive session. The user reports this is recurrent. After the crash the session had to be resumed, and the previous background agent was no longer accessible from the resumed session.
Environment
- Copilot CLI: 1.0.109
- OS: Linux (Rocky Linux 9)
- Workload: long interactive session with prior context compaction and background agent work
Expected
The CLI remains responsive, or recovers without losing access to in-progress work.
Actual
The CLI crashed with an out-of-memory condition. Exact allocation, stack trace, trigger, and reproducible steps have not been independently established; this report does not assert a root cause. No diagnostic logs are included.

Another recurrence reported on 2026-11-12 at approximately 14:17 PST (22:17 UTC), during the same long-running interactive session.
User-supplied V8 GC diagnostics, verbatim:
The diagnostics show roughly 3.96 GB remaining after a major collection at approximately 6 hours 46 minutes of process uptime. They are consistent with substantial retained heap and allocation pressure, but do not establish a leak, the exact heap limit, or a root cause. No actual core file, fatal-error line, or native stack trace was supplied.
Recovery observation: the resumed assistant could recover persistent task records and files, but three known in-flight background-agent IDs were no longer found, and no prior polling shell remained active. Independently running application containers remained healthy; their health does not diagnose the CLI crash.
