Hi guys,
Got an odd thing going on right now. Indexing into my master server (solr
3.6.1) has slowed and it is because when solr runs ping shows latency. When I
stop solr though, ping returns to normal. This has been happening
occasionally, rebooting didn't help. This is the first time I noticed that
stopping solr returns ping speeds to normal. I was thinking it was something
with our network. Solr is not consuming all resources on the box or anything
like that, and normally everything works fine. Has anyone seen this type of
thing before? Let me know if more info of any kind is needed.
Solr process is at 8% memory utilization and 35% cpu utilization in 'top'
command.
Note: solr is the only thing running on the box.
