Dear @Surabhi_Katiyar , @Vijayalakshmi_S , @Varun_Shakya , @arunpatidar Thank you so much for your valuable inputs, I have found the root cause(apparently). I have some custom index definitions and they are inside the /oak:index content.xml. Here is how it's in my project :
<myCustomLuceneIndex
jcr:primaryType="oak:QueryIndexDefinition"
async="async"
compatVersion="{Decimal}2"
excludedPaths="[/content/myApp/sites/en-us/system-pages,/content/myApp/sites/en-us/miscellaneous"
excludePropertyNames="[cq:lastModifiedBy,jcr:createdBy,cq:lastReplicatedBy,jcr:lastModifiedBy]"
indexPath="/oak:index/myCustomLuceneIndex"
includePropertyTypes="[String,Binary]"
reindex="{Boolean}false"
reindexCount="{Long}2"
type="lucene">
<indexRules jcr:primaryType="nt:unstructured">
<nt:base
jcr:primaryType="nt:unstructured"
includePropertyTypes="[String,Binary]">
<properties jcr:primaryType="nt:unstructured">
<allProps
jcr:primaryType="nt:unstructured"
isRegexp="{Boolean}true"
name=".*"
nodeScopeIndex="{Boolean}true"/>
</properties>
</nt:base>
</indexRules>
</myCustomLuceneIndex>
When I remove my index definition <filter root="/oak:index/myCustomLuceneIndex"/>) from filter.xml, the issue doesn't happen and I see the pages load, login page opening, etc. but yeah, I see warnings in error.log(..consider creating an index).
I have created a package of my custom index definitions. I install that(explicitly, not a part of build)and manually trigger reindexing and that works.
This works fine in AEM6.4.4 but on AEM6.5.5, seems like the engine gets stuck somehow and not being able to recover at all(even after AEM restart, or system restart). Why is that? is this way not recommended? or am I doing something wrong?
Thanks again,
Bilal.
