Re: Solr Replication sometimes coming in log files
I bet you have the admin UI open on your second slave. The _=144... is
the give-away. Those requests are the admin UI asking the replication
handler for the status of replication.

Re: Solr Replication sometimes coming in log files
Hello,
I'd say opposite: high load causes long time to respond. 'command=details'
is rather cheap and fast _I believe_.

Solr Replication sometimes coming in log files
Hi Team,
I am currently working with Java-1.7, Solr-4.8.1 with tomcat 7. The solr
configuration has master & slave ( 2 Slaves) architecture.
Master & Slave 2 are in same server location (say zone A) , whereas Slave 1
is in another server in different zone (say zone B). There is latency of 40
ms between two zones.
Now, a days we are facing high load on Slave 1 & we suspect that it is due
to delay in data replication from Master server. These days we are finding
these below mentioned replication information in log files, but such lines
are not in previous files on the Slave 1 server. Also, such information is
not there in any Slave 2 log files (might be due to same zone of master &
slave 2).

Please confirm if we our thought that increased replication time (which can
be due to servers connectivity issues) is the reason for high load on solr.
