[yuhuangbin]

Is it normal to use tomcat?

[waming5]

Is it normal to use tomcat?

tomcat doesn't have this problem。

[yuhuangbin]

This problem occurs when the application is stopped and does not affect actual use, which we will troubleshoot later.

[yiminyangguang520]

@yuhuangbin I meet the same problem, when to slove the problem? wait for your replay, thank you! environment: spring cloud: 2020.3 spring cloud alibaba: 2021.1 spring boot: 2.4.6

[jsczrangel]

it shows when i used undertow rather than tomcat,how can i fix it

[yujianweilai]
