> When I was performing [Spring Session and Kubernetes Rolling Update demo|https://bluejeans.com/s/pYKUg/] I encountered a couple of problems.
> One of the is this:
> {noformat}
> [transactions-repository-1-hqz3v] *** JBossAS process (83) received TERM signal ***
> [transactions-repository-1-dwl81] 09:52:09,522 INFO  [org.jboss.as.server] (Thread-2) WFLYSRV0220: Server shutdown has been requested via an OS signal
> [transactions-repository-1-dwl81] *** JBossAS process (80) received TERM signal ***
> [transactions-repository-1-hqz3v] 09:52:09,526 INFO  [org.jboss.as.server] (Thread-2) WFLYSRV0220: Server shutdown has been requested via an OS signal
> {noformat}
> Full logs from Rolling Update process might be found here: https://gist.github.com/slaskawi/2308b4c5e9bbf523fb3e02a7cc45fa24
> Steps to reproduce:
> * Start local OpenShift Cluster
> * invoke `./init_infrastructure.sh` from https://github.com/slaskawi/presentations/tree/ISPN-7487-reproducer
> * invoke `cd transaction-creator && mvn fabric8:run`
> * Start Spring Session Demo `cd session-demo && mvn fabric8:run`
> * Create a client which inserts data (`watch -n 0.5 curl http://<spring-session-demo-pod-ip>/sessions`) and at the same time invoke the rolling update: `oc deploy transactions-repository --latest -n myproject`
> * Observe logs `kubetail -l environment=infrastructure`
