every now and then and on every slave randomly. However I haven't seen any issues with replication of Master-Slave as such , validated with Index Version and Generated numbers as well as the data.

I am using solr3.5 with 5Slaves + 1Master. Polling interval being 20seconds and docs are updated(delta-import) every 60 seconds through Master. Slaves only are for read.

I am running solr with tomcat 6.0.35 + Java 6 and below is the connection settings

<Connector port="8080" maxHttpHeaderSize="8192"
maxThreads="200" minSpareThreads="25" maxSpareThreads="75"
enableLookups="false" redirectPort="8443" acceptCount="100"
connectionTimeout="20000" disableUploadTimeout="true" />

Heap size is 1Gb( Xms=Xmx=1024m).
