Quick question about Predictive Routing outbound campaign updates failing under load.
JMeter 5.6.2 from Singapore hitting POST /api/v2/predictiverouting/outboundcampaigns. Single thread works fine. At 50 concurrent threads, getting 503 Service Unavailable on the initial request, not just rate limiting.
jmeter_config:
thread_count: 50
ramp_up: 10
loop_count: 1
target_endpoint: /api/v2/predictiverouting/outboundcampaigns
region: us-east-1
Is there a hard limit on concurrent campaign creation requests per org? Or is this a backend timeout issue?
