24/7 ActiveMQ Support with a 15-Minute Emergency SLA

AceMQ supports both ActiveMQ Classic and ActiveMQ Artemis in production — KahaDB corruption, producer flow control stalls, broker network splits, and JDBC store contention. Every ticket reaches a named senior engineer who already knows your broker topology.

Escalation Path

Your first hour of a ActiveMQ outage

Most vendors publish an SLA number. This is what actually happens, minute by minute, when you page a senior AceMQ engineer.

T+0

You page us

Phone, email, or Slack — any channel reaches the on-call senior engineer directly. No web form, no tier-1 queue.

T+15

Named engineer live

A senior engineer who already knows your environment joins a live bridge. Zero cold-start, no re-explaining your topology.

T+30

Root cause isolated

Direct broker access, log and metric review, and a working hypothesis with a rollback plan before we touch anything.

Post

Written RCA

Documented root cause, the fix applied, and the prevention steps — delivered after every P1, not just when asked.

Response Times

SLA tiers, contractually guaranteed

Every tier reaches a senior ActiveMQ engineer. There is no tier-1 triage layer to get through.

P1 — Emergency
15 min

Production down, messages not flowing, cluster or broker failure

P2 — Critical
1 hour

Severe degradation, rising error rates, approaching capacity limits

P3 — High
4 hours

Performance issues, configuration problems, non-critical failures

P4 — Standard
Next day

Questions, guidance, best practices, non-urgent improvements

Incident Triage

ActiveMQ problems we fix every week

These are real symptoms from real ActiveMQ production environments — and the first thing our engineers check when one comes in.

Producers hang or block — messages stop flowing with no error
What we check firstProducer flow control state and memory/store/temp usage limits. In Classic this is almost always a destination hitting its memoryLimit with a slow or stalled consumer behind it.
Typical resolutionUnder 1 hour
KahaDB journal growing without bound, disk filling up
What we check firstWhich journal files are pinned and why — usually one unacknowledged message or a stuck durable subscriber holding a reference and preventing cleanup of every file after it.
Typical resolution1–3 hours
Broker OutOfMemoryError under normal message volume
What we check firstConsumer prefetch sizes against JVM heap. A default prefetch of 1000 across many consumers on large messages will exhaust heap long before the broker's own memory limits engage.
Typical resolutionUnder 2 hours
Messages stuck in a redelivery loop, DLQ growing fast
What we check firstRedelivery policy, poison-message handling, and whether the consumer is throwing before or after acknowledgement — plus transaction boundaries if XA is involved.
Typical resolution1–2 hours
Network of brokers split-brain — duplicate or stranded messages
What we check firstNetwork connector configuration, duplex settings, and advisory message flow. Misconfigured networkTTL and conduitSubscriptions are the usual cause of message duplication across a broker mesh.
Typical resolution2–4 hours
Artemis address full, paging to disk, throughput collapsing
What we check firstAddress settings — max-size-bytes, address-full-policy, and page-size-bytes — against actual consumer drain rate. Paging masks a consumer that can't keep up.
Typical resolutionUnder 2 hours
Failover not working — clients don't reconnect to the slave
What we check firstShared-store vs. replication topology, file lock acquisition on the shared store, and whether the client URI actually lists the failover transport with both brokers.
Typical resolution2–4 hours

Resolution times reflect typical ActiveMQ engagements under an active AceMQ support contract. Every P1 closes with a written root-cause analysis.

What's Included

Everything in your ActiveMQ support contract

No add-on pricing for incidents. No per-ticket charges. One contract covers the whole surface.

Emergency Incident Response

Production down, messages not flowing, or a broker that won't start. A senior engineer joins a live bridge within 15 minutes with direct access to diagnose — not a ticket acknowledgement.

Root Cause Analysis

Every P1 closes with a written RCA: what failed, why, the fix applied, and the specific configuration or code change that prevents recurrence. Delivered as standard, not on request.

Performance Tuning

Prefetch sizing, memory and store limits, KahaDB vs. JDBC persistence selection, and consumer concurrency tuned against your actual throughput profile and message sizes.

CVE & Patch Advisory

Proactive alerts for CVEs affecting your exact ActiveMQ version — including the 2023 CVE-2023-46604 class of RCE issues — with tested upgrade paths and mitigation guidance.

Capacity & Scaling Reviews

Quarterly reviews of queue depth trends, broker resource headroom, and destination growth so you size ahead of demand rather than reacting to a full store.

Upgrade & Migration Support

ActiveMQ Classic to Artemis migration planning, version upgrades with rolling procedures, and migration off ActiveMQ to RabbitMQ or Kafka where that's the right call.

Anywhere You Run It

We support ActiveMQ wherever it's deployed

Cloud, Kubernetes, bare metal, hybrid, and air-gapped — including environments where you can't give us outbound network access.

Why AceMQ

What you get that you don't get elsewhere

Named Engineers, Zero Cold Start

The same senior engineers stay on your account. They know your broker topology, your persistence choice, and your traffic pattern — so a P1 call starts with diagnosis, not twenty minutes of you explaining your environment.

No Tier-1 Triage Layer

You reach a senior ActiveMQ engineer directly by phone, email, or Slack. There is no help desk collecting information to pass along, and no escalation approval process standing between you and someone who can actually fix it.

Classic and Artemis, Both Deeply

Most vendors know one. We support ActiveMQ Classic 5.x and Artemis 2.x in production, including the migration between them — which matters because the two share a name and almost nothing else architecturally.

Genuine Follow-the-Sun Coverage

Engineers across 26+ countries and every time zone. Your 3am incident is someone's mid-afternoon — no overnight skeleton crew, no waiting for a region to wake up.

Proactive, Not Just Reactive

Quarterly health checks on your deployment plus shared intelligence across our support base. When a version-specific bug surfaces on one customer's cluster, every affected customer hears about it before it reaches their production.

Full-Stack, Not Just the Broker

ActiveMQ problems are often not ActiveMQ problems. We diagnose across the JVM, the OS, storage latency, network policy, and Kubernetes — because that's where the root cause frequently actually lives.
