Backlog: Stress test performance failure

TL;DR

QA stress test (500 concurrent virtual users) reported system failure under load on the Claim payment-request flows; capture specifics still pending.

Description

  • Source: QA.
  • Finding: Performance / stability failure under concurrent load on Claim.
  • How found: Stress testing with 500 virtual users.
  • Result: System failed under that load — document error types, SLA thresholds, stack traces, and environment when known.

Acceptance Criteria

  • Failure reproduced or ruled out with documented scenario
  • Bottleneck identified (app, DB, integration, infra)
  • Fix validated against agreed concurrency target or documented limits

Priority

  • Priority: p1
  • Rationale: Payment-request pipeline touches approvals and finance inbox — outage risk under peak usage.
