Vadym Lotar commented on SOLR-5364:
-----------------------------------
Greetings,
We are experiencing completely the same problem with our environment:
SOLR 4.5.1
Open JDK version "1.7.0_25"
30Gb RAM
Default JAVA_OPTS
2 shards
2 slaves for each shard
3.5.0-36-generic #57~precise1-Ubuntu
Our first step would be changing GC algorithm, however it seems that we have a
deadlock somewhere during writing the index.
Could we provide any information which can be useful for investigating this
problem?
Thanks in advance.
> SolrCloud stops accepting updates
> ---------------------------------
>
> Key: SOLR-5364
> URL: https://issues.apache.org/jira/browse/SOLR-5364
> Project: Solr
> Issue Type: Bug
> Components: SolrCloud
> Affects Versions: 4.4, 4.5, 4.6
> Reporter: Chris
> Priority: Blocker
>
> I'm attempting to import data into a SolrCloud cluster. After a certain
> amount of time, the cluster stops accepting updates.
> I have tried numerous suggestions in IRC from Elyorag and others without
> resolve.
> I have had this issue with 4.4, and understood there was a deadlock issue
> fixed in 4.5, which hasn't resolved the issue, neither have the 4.6 snapshots.
> I've tried with Tomcat, various tomcat configuration changes to threading,
> and with Jetty. Tried with various index merging configurations as I
> initially thought there was a deadlock with concurrent merg scheduler,
> however same issue with SerialMergeScheduler.
> The cluster stops accepting updates after some amount of time, this seems to
> vary and is inconsistent. Sometimes I manage to index 400k docs, other times
> ~1million . Querying the cluster continues to work. I can reproduce the
> issue consistently, and is currently blocking our transition to Solr.
> I can provide stack traces, thread dumps, jstack dumps as required.
> Here are two jstacks thus far:
> http://pastebin.com/1ktjBYbf
> http://pastebin.com/8JiQc3rb
> I have got these jstacks from the latest 4.6 snapshot, also running solrj
> snapshot. The issue is also consistently reproducable with BinaryRequest
> writer.
