Mysterious Solr crash
Good morning
I am running a batch indexing job and Solr core mysteriously shut down
without any particular error. How can I investigate this? I am focusing on
the line which mentions "Shutting down CoreContainer instance".
There are errors soon after that, but they seemed to be caused by the core
shutting down and not the other way round; although i can be wrong.
Thanks
Nawab

And early EOF in the middle of an impasse usually indicates a timeout
either from client to server or between servers in an update chain. Try
increasing the timeout.

Re: Mysterious Solr crash

Looking at the stack trace, which seem truncated, I would start from here
o.a.s.h.RequestHandlerBase org.apache.solr.common.SolrException: Early EOF
at org.apache.solr.handler.loader.XMLLoader.load(XMLLoader.java:190)
Could you please expand a bit your context (e.g. solr version, cloud / no
cloud, xml data size, indexing client type). Also, the whole stacktrace
(unless it is huge), should be helpful, too.
Best,
Andrea

Hi,
Which version of Solr are you running on? And also, are you running on
SolrCloud or Standalone Solr?

Re: Mysterious Solr crash
Posted by Nawab Zada Asad Iqbal <kh...@gmail.com>.
I am using 7.0.1 without SolrCloud (sorry for missing that detail earlier).
I totally agree with you, Shawn. An crash after an OOM is not graceful like
this and it usually has an incomplete logline in the end.
I tried to only copy the log which seemed related to this issue, I will see
if I find any other meaningful part and will copy here.

Crashes in Solr are extremely rare. If it actually does happen, it
would probably be caused by severe issues with Java or the operating
system, or hardware problems like failing memory chips.
If you've got a recent version of Solr and it's running on an OS that's
NOT Windows, then an OutOfMemoryError is likely going to result in Solr
being killed. But if that happens, all logging stops -- Solr will not
log anything about the CoreContainer shutting down.
The most likely cause here is that something triggered the shutdown hook
in Solr, which caused an orderly shutdown of the CoreContainer, so you
got that log message. In a nutshell, Solr shut down because something
external explicitly told it to shut down.
Can you share the entire solr.log file? I can't guarantee that the file
will have anything in it that explains what went wrong, but we can look.
Thanks,
Shawn
