Solr6 producing lots of error logs

[dsc1086]

Hello everybody,

In the solr6 webconsole, the logging is producing lots of errors, doing rollbacks mainly because of the following error : 

java.lang.NullPointerException
at org.alfresco.solr.tracker.MetadataTracker.setLastTxCommitTimeAndTxIdInTrackerState(MetadataTracker.java:1023)
at org.alfresco.solr.tracker.MetadataTracker.checkRepoAndIndexConsistency(MetadataTracker.java:404)
at org.alfresco.solr.tracker.MetadataTracker.trackRepository(MetadataTracker.java:282)
at org.alfresco.solr.tracker.MetadataTracker.doTrack(MetadataTracker.java:242)
at org.alfresco.solr.tracker.AbstractTracker.track(AbstractTracker.java:242)
at org.alfresco.solr.tracker.ActivatableTracker.track(ActivatableTracker.java:97)
at org.alfresco.solr.tracker.TrackerJob.execute(TrackerJob.java:60)
at org.quartz.core.JobRunShell.run(JobRunShell.java:202)
at org.quartz.simpl.SimpleThreadPool$WorkerThread.run(SimpleThreadPool.java:573)

Does anybody have an idea how to solve this?

Do you have some customized configuration in solrcore.properties for the following parameters?

"solr.initial.transaction.range"

"solr.initial.transaction.id"

What Search Services version are you using?

[dsc1086]

Hello,

Indeed I have the following configuration, which has been the initial config of the file:

solr.initial.transaction.range=0-2000

I am using Search Services 2.0 and installed it according to this tutorial : Alfresco Docs - Installation options

[dsc1086]

Here is also now the second error message I get in the solr console :

Then I guess that the main problem is that SOLR is not able to communicate with Alfresco Repository, likely due to a missconfiguration of TLS communication or incorrect Alfreso Repository server URL, port and protocol in SOLR side.

[dsc1086]

The repository configuration should be good as I was able to do a re-index. That should not be possible otherwise.

This is my Configuration in the alfresco-global.properties file:

solr.secureComms=none
solr.host=localhost
solr.port=8983
solr.port.ssl=8983
index.subsystem.name=solr6
solr.baseUrl=/solr

An this is my solrcore.properties-file : 

# none, https
alfresco.secureComms=none

# ssl, default values
# keystore and trustore files are not provided by default
alfresco.encryption.ssl.keystore.type=JCEKS
alfresco.encryption.ssl.keystore.provider=
alfresco.encryption.ssl.keystore.location=/data/alfresco/alfresco-7.0.1.3/alfresco-search-services/solrhome/keystore/ssl.repo.client.keystore
alfresco.encryption.ssl.keystore.passwordFileLocation=
alfresco.encryption.ssl.truststore.type=JCEKS
alfresco.encryption.ssl.truststore.provider=
alfresco.encryption.ssl.truststore.location=/data/alfresco/alfresco-7.0.1.3/alfresco-search-services/solrhome/keystore/ssl.repo.client.truststore
alfresco.encryption.ssl.truststore.passwordFileLocation=
alfresco.port.ssl=8443

Do you see any inconsistency?

[angelborroy]

Is Alfresco repository running in http://localhost:8080/alfresco?

[dsc1086]

localhost:8080/alfresco is the alfresco main page :

The repository is stored under a "/data/alfresco/alf_data/contentstore" - folder and can be accessed by http://servername:8080/shared.
Solr and alfresco are running on the same server.

[dsc1086]

Here is my config in the admin console:

[dsc1086]

Hello Angel,

After re-indexing, my search - function in ACS 7 is working now, so solr seems working good.
However I still get numerous times the same error message below.

Do you can help me with this?
