Hello! Yesterday Content Lifecycle Project build failed without any additional information. It was our test environment and it was never happened before. I (re)synced all source repos by hand (just in case) and after that build succeeded and all seemed to be ok. I was a bit hurry and I didn't find any errors in log files at first glance so I leave it... This morning I encountered same "failed" notice in our production Uyuni server. This time I clicked "Build" again without additional repo resync and the second build succeeded. However repository content seems to be somewhat messed up, in both Uyuni servers. Client servers found a lot of updates, mainly different Perl packages but couldn't update because of many conflicting dependencies. There is a lot of Perl 5.30 -version updates available even if I have not enabled this module stream. Default Perl version branch in Redhat EL8 derived distributions is 5.26 and additional versions is provided with module streams. Currently installed Perl version in my servers is 5.26. In fact there isn't any filters concerning Perl at all in this Content Lifecyle Project. I found errors in /var/log/rhn/ rhn_web_ui.log -file corresponding the failed environment build: 2022-02-08 07:03:03,580 [RHN Message Dispatcher] ERROR com.redhat.rhn.frontend.events.TransactionHelper - com.redhat.rhn.frontend.events.AlignSoftwareTargetAction$AlignSoftwareTargetException: java.lang.StackOverflowError 2022-02-08 07:03:03,656 [RHN Message Dispatcher] ERROR com.redhat.rhn.frontend.events.AlignSoftwareTargetAction - Error aligning target 3 com.redhat.rhn.frontend.events.AlignSoftwareTargetAction$AlignSoftwareTargetException: java.lang.StackOverflowError at com.redhat.rhn.frontend.events.AlignSoftwareTargetAction.execute(AlignSoftwareTargetAction.java:71) at com.redhat.rhn.common.messaging.ActionExecutor.lambda$run$0(ActionExecutor.java:67) at com.redhat.rhn.frontend.events.TransactionHelper.run(TransactionHelper.java:63) at com.redhat.rhn.frontend.events.TransactionHelper.handlingTransaction(TransactionHelper.java:47) at com.redhat.rhn.common.messaging.ActionExecutor.run(ActionExecutor.java:67) at com.redhat.rhn.common.messaging.MessageDispatcher.run(MessageDispatcher.java:91) at java.base/java.lang.Thread.run(Thread.java:829) Caused by: java.lang.StackOverflowError at java.base/java.util.function.Predicate.lambda$or$2(Predicate.java:101) at java.base/java.util.function.Predicate.lambda$or$2(Predicate.java:101) at java.base/java.util.function.Predicate.lambda$or$2(Predicate.java:101) Last message continues about thousand lines. Is there any other log files I should check? We are using openSUSE Leap 15.3 and Uyuni 2022.01 version. All the client servers and repositories/channels are Rocky Linux 8. I think we must ditch current Lifecycle Environment and build totally new for our Rocky Linux servers. I wonder however is this a bug or is there something we should do differently this time to avoid this kind of errors?
