Crash reports collection Q1 2026

@sky-runner I second this. In my case it happend 3 times over 18 months or so.

Problem with those race conditions is that there is seldom something you can do to avoid them - on the user side.

My suunto vertical 1 crashed last weekend while manipulating suunto plus app.

Today crashed again while zooming out during my stand paddle activity (no Suunto app enabled) I sent the logs today.

Hi @Dimitrios-Kanellopoulos

I’ve had the same issue with my Suunto 9 Peak Pro - happening mid workout and at the START screen.

I’ve contacted support but heard nothing back yet.

I suspect the 9PP shares a similar code base to the Vertical 1.

Let me know how I can send over diagnostics - I’m a developer so familiar with application support diagnostics.

Race S

Yes it’s in there ta buddy - sent Suunto account details via chat.

For me the freezing issue is very likely a faulty garbage-collection issue with a SuuntoPlus app I wrote leading to RAM pressure, can easily reproduce and send logs over so that a firmware update can isolate any app issues from the actual watch.

Had a crash during my run today, using a Race 2. It crashed at just after 2Km into the run.
I had 3 S+ apps enabled (Cadence coach, ZoneSense and Running Economy) and was using a Polar H10 belt. Everything else were standard (no nav, battery on performance, feeling on, no music controls, etc).

When I realise the watch had crashed and restarted, I’ve started a new activity to continue my run. However, this time I unselected the ZoneSense app, while keeping the other 2 S+ apps and the HR belt. The remaining 10.4Km went well, no problems.

Hope this gets sorted soon by the team.

@jjorgemoura try to disable ZoneSense from your S+ apps. It seems it helps me with my Race S.

I’m still experiencing random restarts on my Vertical 2. Yesterday, it happened three times in a single day. Fortunately, not during an activity. I have the latest firmware installed.
Question: Should I keep sending the logs, or is the cause of the problem already known?

Hi Suunto Team,

I encountered my first unexpected watch shutdown after updating to software version 2.56.18.

It happened during today’s run at 6.41 km while I was using SuuntoPlus Fused Zone together with a Suunto Heart Rate Belt.

Has anyone else experienced this issue? Is there a recommended fix or troubleshooting step? I’d really like to avoid this happening during an upcoming race.

Thanks in advance for your help

Yes, keep sending logs unit suunto confirms they know the cause.
And send an email to support@suunto.com from the same email address as is configured in your suunto profile. That way they connect the logreport with your bugreport in email.
