Hi all, my XWiki installation is constantly crashing. Several times each hour. For two users which don’t even really use the Wiki this is absolutely inacceptable.
Problem is - I don’t know why. The only thing I did was LDAP authentication, after trying (and failing) with OpenID connect authentication (I disabled the latter plugin again after LDAP worked).
I’ve checked the logs and there’s a broken pipe between Tomcat and browser or any server in between your browser and Tomcat. So you should check/fix this. XWiki is trying to return data to the client side and Tomcat is saying that the connection to the client side is dead (in general this means the client side disconnected).
Well. The wiki becomes unresponsive, and after a couple of seconds I get the “Wiki initializing (%…)” screen. To me that’s a crash, but you’re right that was not fully precise.

Very weird. Nothing fancy going on here. Any hints on how that can happen?
UPDATE: maybe I should be more preceise again . Some context: I run XWiki in Kubernetes, using the “standard” nginx-ingress-controller from Helm, and ACME encryption using cert-manager. All of that runs in Azure, with an initial load balancer in front of everything.
Nothing here is unusually configured, there are no long running requests, and the cluster is basically empty execpt for XWiki (as of now ).
