Your application was recycled due to an intermittent Azure infrastructure issue while accessing remote file storage. This event occurred multiple times during the day across multiple instances. This can happen due to multiple reasons like platform instances getting upgraded or instance(s) experiencing high latencies accessing the remote storage. In case the instance(s) where your application is running is experiencing high latencies accessing remote storage, the platform tries to heal your application by switching to different remote storage which is having low latency. This can also cause the application process to restart. If this is a one off occurrence, then no further action plan is needed from your side. But if you see it occur frequently, then enabling local cache feature can help reduce dependency on storage file servers to some extent.

Hi @Bhupendrakumar Jesalpura

Thanks for sharing the details. I’m sorry to hear your application is getting restarted frequently due to remote storage access issues.

This is a known behavior in Azure App Service. When the platform detects high latency or intermittent problems connecting to the shared file storage, it automatically recycles the app and moves it to a better storage endpoint. While this protects the app’s health, it can cause restarts if it happens often.

Recommended Solution: Enable Local Cache. This makes your app run from a local copy on the instance’s fast SSD, significantly reducing dependency on remote storage and preventing these recycles in most cases.

Quick Steps to Enable Local Cache:

Go to your App Service > Configuration > Application settings.

Add the following setting:

Name: WEBSITE_LOCAL_CACHE_OPTION

Value: Always

(Optional but recommended) Add:

Name: WEBSITE_LOCAL_CACHE_SIZEINMB

Value: 1000

Save and restart the app.

Bhupendrakumar Jesalpura hi & thx for join us here at Q&A platform,

yeah this one is classic App Service behavior, nothing “broken” but annoying af. ur app is tied to remote storage (the shared file system behind App Service) if that storage gets slow or Azure moves u to another backend app restarts. Thats what that message is saying in human terms “storage was slow or moved we recycled ur app to fix it” . Why it happens repeatedly, storage latency spikes, platform upgrades, underlying instance swap and bc all instances share that storage u see it across multiple instances. Real fix here is reducing dependency on that storage main thing, try to enable Local Cache, that basically copies ur site to local disk on the instance app runs from there less dependency on remote file share fewer restarts, other things that may help are

dont write temp/runtime stuff to shared storage (use /tmp or in-memory)

move sessions to Redis instead of file system

avoid heavy IO on wwwroot

if its happening a lot (not just once) then yeah its not “ignore it” situation, its stability issue

rgds,

Alex

Hello @Golla Venkata Pavani

Can we verify from where storage latency spikes happens , is platform upgrades happens , and underlying instance swap and bc all instances share that storage u see it across multiple instances.

Hi @Bhupendrakumar Jesalpura

Thanks for the question

In Azure App Service, all instances share the same platform-managed content storage (Azure Files). That’s why latency spikes or connectivity issues affect multiple instances simultaneously, leading to the restarts you’re seeing.

The platform automatically heals by recycling the app and moving it to a healthier storage backend. This commonly happens during file server maintenance, upgrades, or transient infrastructure events. Unfortunately, the exact source of the latency (specific file server or internal swap) is not exposed in customer logs or metrics. However, the Diagnose and solve problems blade (especially the Web App Restarted detector) will usually confirm it was a platform-initiated event.

Microsoft recommends enabling Local Cache specifically for this scenario. It creates a fast local SSD copy of your site content on each instance, making your app largely immune to remote storage latency issues.

This change significantly reduces (and in most cases eliminates) storage-related restarts. You may still see occasional restarts during major platform maintenance, but they become far less frequent.
