Hi, We are getting 504 Gateway Timeout server error when trying to access AEM author instance in our stage author environment. In error logs we see following "Failed to create checkpoint warning messages when this happens: 14.10.2020 04:01:01.940 *WARN* [sling-oak-54-org.apache.jackrabbit.oak.plugins.index.AsyncIndexUpdate-async] org.apache.jackrabbit.oak.segment.scheduler.LockBasedScheduler Failed to create checkpoint 8a02222a-3c8d-44dc-8066-05e78ea31fad in 10 seconds.14.10.2020 04:01:01.940 *W...

@SundeepKatepallyAnother interesting thing to note is, on a fresh instance it takes only 5-7 minutes to complete the deployment. If it's a consistent product issue, it should happen even on a fresh instance as well. I doubt if there are more conditions involved when this is supposed to occur. May be when you have lot of content/asserts available in the repository.

Thanks @SundeepKatepally for your valuable inputs. It helps. We also have a ticket raised with AMS to help us investigate the issue and its been few weeks now, but they have not informed about this product issue yet. It is now a business critical issue for us, as we are not sure what are other impacted areas, if any. It seems like we have to live with it until they provide us a fix for the same.

Thanks @SundeepKatepally for your response. Did you also encounter that sometimes it results in server becoming unresponsive? I have worked with 6.4.2 version in two other projects but have not faced this issue there. Does it happen in any specific scenario? Moreover our author takes around 10-15 minutes to come back but publisher usually take 30-40 minutes.

Hi, We are facing following two unusual environment issues in our AMS managed stage environments:With deployment either of author or publisher instances becomes unresponsive and service restart is the only option to bring them back-upDeployment takes longer time 30-40 minutesAfter Analyzing logs we found that AEM restarts many of its services and sometimes these restart of services is multiple times. This is one of the reason for long deployment duration we are facing. Our deployment package siz...
