Solr 6.1 Prod Issue | KeeperErrorCode = ConnectionLoss for
/overseer_elect/leader
Hello
Sorry for reaching out on this email but I wasn't getting any traction on the other distribution list. Please find logs of our Solr Prod Outage Attached.
We are looking into some of the posts that have been suggested but they don't seem to be matching completely as per our current analysis. We are still working on analyzing the Heap Dumps on how GC is working. We are also looking into why packets are being dropped on the zookeeper nodes.
What we are now seeing are three other things:
[ERROR] 2017-07-05 01:57:51 (SolrException.java:log:159) - :org.apache.zookeeper.KeeperException$ConnectionLossException: KeeperErrorCode = ConnectionLoss for /overseer/collection-queue-work - Only Once
[ERROR] 2017-07-05 01:58:19 (OverseerTaskProcessor.java:amILeader:392) -
org.apache.zookeeper.KeeperException$ConnectionLossException: KeeperErrorCode = ConnectionLoss for /overseer_elect/leader - Multiple times for all collections which have shards on that Solr Node.
34811545 [qtp778720569-21] [ERROR] 2017-07-05 02:01:08 (SolrException.java:log:148) - java.io.IOException: Error opening /configs/feedsInBoundNonEx/db-data-config.xml - For all collections which have shards on that node.
If any of you have seen this error before and have any suggestions. Please let me know.
Thanks,
Rahat Bhalla

From the fact that someone has tried to access /etc/passwd file via
your Solr (see all those WARN messages), it seems you have it exposed to
the world, unless of course it's a security scanner you use internally.
Internet is a hostile place, and the very first thing I would do is
shield Solr from external traffic. Even if it's your own security
scanning, I wouldn't do it until you have the system stable.
Doing the above you'll reduce noise in the logs and might be able to
better identify the issue.
Losing the Zookeeper connection is typically a Java garbage collection
issue. If GC causes too long pauses, the connection may time out. So I
would recommend you start by reading
https://wiki.apache.org/solr/SolrPerformanceProblems and
https://wiki.apache.org/solr/ShawnHeisey. Also make sure that
Zookeeper's Java settings are good.

Hi
I'm not sure if any of you have had a chance to see this email yet.
We had a reoccurrence of the Issue Today, and I'm attaching the Logs from today as well inline below.
Please let me know if any of you have seen this issue before as this would really help me to get to the root of the problem to fix it. I'm a little lost here and not entirely sure what to do.
Thanks,

Subject: Solr Prod Issue | KeeperErrorCode = ConnectionLoss for /overseer_elect/leader
Importance: High
Hi Solr Users,
I hope this email finds you all in the best of spirits and in a mood where you'd be willing to help a young developer (me :) ) with issues that I'm facing in regards with the Solr Cloud.
At my organization, we are running a Solr Cloud with 5 Nodes for Solr Instances with 13 collections spread across the 5 nodes and an ensemble of 3 zookeeper instances spread across three different nodes.
Over the last one week, our leader node seems to be going down every other day and while we restart the solr instances they still go down within the next 24 Hours or more.
We have tried rebooting the nodes that host the solr instances and that hasn't helped. We plan to clear out the zookeeper logs and data folders before the restart of the zookeeper instances.
As of now, I'm the only one supporting Solr in my organization and any insight from you could help me a great deal to fix the issue. I'm copying the Exception stack trace from this morning. Any recommendations that you might have will be great appreciated.
Below is a snapshot of one of the zoo nodes:

Re: Solr 6.1 Prod Issue | KeeperErrorCode = ConnectionLoss for
/overseer_elect/leader
Posted by Jan Høydahl <ja...@cominvent.com>.
I’m sorry, but this discussion belongs on the solr-user list.
You may try to jump on the IRC chat http://www.cominvent.com/support/solr-irc/ <http://www.cominvent.com/support/solr-irc/> in hope to get someone chatting with you in real time.
But if this is urgent for your company the best advise I can give is to hire professional support, see https://wiki.apache.org/solr/Support <https://wiki.apache.org/solr/Support>

> Hi Solr Users,
>
> I hope this email finds you all in the best of spirits and in a mood where you’d be willing to help a young developer (me J ) with issues that I’m facing in regards with the Solr Cloud.
>
> At my organization, we are running a Solr Cloud with 5 Nodes for Solr Instances with 13 collections spread across the 5 nodes and an ensemble of 3 zookeeper instances spread across three different nodes.
>
> Over the last one week, our leader node seems to be going down every other day and while we restart the solr instances they still go down within the next 24 Hours or more.
>
> We have tried rebooting the nodes that host the solr instances and that hasn’t helped. We plan to clear out the zookeeper logs and data folders before the restart of the zookeeper instances.
>
> As of now, I’m the only one supporting Solr in my organization and any insight from you could help me a great deal to fix the issue. I’m copying the Exception stack trace from this morning. Any recommendations that you might have will be great appreciated.
>
