    Frequent restarts of Umbraco - out of memory exception (sometimes)

    Frequent restarts of Umbraco

    Summary

    Azure hosted umbraco site. The slave portal will often lock up or take a very long time to restart. Often there is nothing in the log to explain why the portal restarted just the fact the portal is starting up but sometimes there is this message:

    [..] ERROR Umbraco.Core.UmbracoApplicationBase - An unhandled exception occurred React.Exceptions.BabelException: Insufficient memory to continue the execution of the program. ---> System.OutOfMemoryException: Insufficient memory to continue the execution of the program.

    However when you look at the server metrics it still has over 10gigs free of available memory. There is no consistency of when the lock up will occur. It does not seem to correlate to peak loads on the server. Restarts can occur when there is little no traffic on the site.

    The illusion is the site is working and delivering pages but in reality its going up and down like a yo yo.

    Specs

    Umbraco Version: 7.15.6 2 x Azure web apps (P3V3) Although the config setup is for load balance scale out there is only a single slave instance. Application insights Version: 2.16.0

    Further details

    When there is no shutdown message and I see "Umbraco 7.15.6 application starting on PC00244D07A4C7" does mean the application terminated unexpectedly and restart is occurring?

    Azure

    Application insights normally captures exceptions (status code 500) when they occur. I have never seen the System.OutOfMemoryException in the AI logs. When I am monitoring the azure live metrics for the slave I can often see the CPU go over 100% and is above 40% most of the time.

    I have reviewed the various pieces of documentation for Umbraco 7 and Azure Web Apps and checked the portals configuration which matches the guides recommendations.

    Site Lock Ups

    I believe occurs when the site has crashed to many times and the examine indexes become corrupt and it takes a long time to rebuild them. During this time the site servers no pages. This can even lock up the master portal.

    Other threads

    I have seen this thread which matches or is very similar to this issue. Sadly they never confirm what was found to resolve the issue.

    Dev

    In local development environment I do not see the same restart behaviour.

    I would appreciate any insights or thoughts on this issue.

    For us this appears to have been Micrsoft Web Optimisation, ScriptBundle vs BabelBundle. A single non react JS file of less than 1mb consumed over 300mb plus of memory. Switching it to ScriptBundle has stopped the constant restarts and the strange memory consumption.
