同遇到

[chickenlj]

I am trying to look into this issue, can u provide any clue on how to reproduce this issue?

[tianshuang]

@chickenlj , same problem, this excepiton keeps appearing after upgrading from 2.7.2 to 2.7.6.

[tianshuang]

I see this warning in the log every time I publish the app.

[tianshuang]

Is it because the service is not offline normally? We have already used QoS to offline the service before publish.

[bigbenfather]

什么原因啊

[wikiwikiwiki]

#6959 里面修复了一下，@chickenlj 看看呢

[kanghuzai]

还有多少坑，从2.7.0踩到2.7.6了
