Spring boot applications sometimes fails to "bind properties" on high load - spring-boot

Question

So every morning we're starting around ~30 spring-boot microservices.
Sometimes one of them is failing to start up.
Running Spring boot 2.1.5.
Today it was with the following error:
2021-11-15 02:18:32.269 INFO 12258023 --- [main] dk.yx.oiltanks.OilTanksApplication : The following profiles are active: prod
2021-11-15 02:19:49.406 ERROR 12258023 --- [main] o.s.b.d.LoggingFailureAnalysisReporter :
***************************
APPLICATION FAILED TO START
***************************
Description:
Failed to bind properties under 'spring.mvc.servlet' to org.springframework.boot.autoconfigure.web.servlet.WebMvcProperties$Servlet:
Reason: Failed to bind properties under 'spring.mvc.servlet' to org.springframework.boot.autoconfigure.web.servlet.WebMvcProperties$Servlet
Action:
Update your application's configuration
Is there any configuration parameters to increase "bind properties" time ?
All we did to get this application running again was starting it with the normal command.
