Is it just me or is Replication a POS? (Solr 1.4.1, Tomcat 6.0.32)
1) I had set my pollInterval to 60 seconds but it appears to fire constantly
so I set it to 5 minutes and I see in the Tomcat logs where it fires the
replication check anywhere from 2 minutes to 4 1/2 minutes, but never
anything remotely consistent and never approaching 5 minutes. What kind of
timer is being used, sundial?
2) When it does fire it seems to do the check between slave and master
anywhere from 3 to 8 times, for a single poll interval. I have 3 slaves and
1 master, the master gets pounded by replication check queries, when it
should get 3 every 5 minutes, it gets up to 24 every couple minutes.
3) Worse of all, there is a replication.properties file on the slaves. It
constantly shows errors, but the tomcat logs on both the slaves and the
master are error free. Below is a representative sample. The timesFailed
number just keeps climbing. The one below went from 10 to 32 in about 8
minutes on the same server, and it should only attempt once every 5 minutes.
#Replication details

replicationFailedAtList= {some long string of large numbers}
previousCycleTimeInSeconds=0
timesFailed=10
indexReplicatedAtList= {some long string of large numbers}
indexReplicatedAt=1305666600335
replicationFailedAt=1305666600335
timesIndexReplicated=10
lastCycleBytesDownloaded=0
Keep in mind, replication actually works! If I add/update a document on the
master i see it on the slaves eventually. So the errors above are especially
frustrating.
Any help on any or all of these issues would be greatly appreciated.
Thanks,
Ken
