Sophos Mobile 8.5 portal not responding and Java process high CPU usage

Mantas L

Hi everybody,

My Sophos Mobile Customers have problem, when try to access SSP or Admin portal. When I started digging in to this problem, I saw high CPU usage (more than 65% of CPU) on Java process in Sophos Mobile server. When I restart Sophos Mobile Service everything works good, and Java process uses only 5-10 % of CPU. How I can troubleshoot this issue? TThis Issue started after Sophos Mobile Server upgrade from 8.1 to 8.5

    After same digging in logs (status.log) I have found error like this:

    <...>Caused by: java.lang.OutOfMemoryError: Metaspace

    I get this solution from Sophos Support:

    Please open the following file on the SMC server with a text editor:% MDM_HOME% \ wildfly \ bin \ standalone.conf.bat
    - Search for -XX: MaxMetaspaceSize = 256m
    - Set the value from 265 to 384 
    - Save the configuration and restart the server completely

    My question was that I can set more than 384m, Sophos Support asnwer was:

    "<..>384m is the recommendation from our developers and you just need to make sure that not too much resources are wasted. <..> However you can set the value to 512m without any issues <..>"
