Hi folks,
In Solr's solr-8983-console.log I see the following (about 50 in a span of
24 hours when index is on going):
WARNING: Couldn't flush user prefs:
java.util.prefs.BackingStoreException: Couldn't get file lock.
What does it mean? Should I wary about it?
What about this one:
118316292 [qtp114794915-39] ERROR org.apache.solr.core.SolrCore [
test_idx] ? java.lang.IllegalStateException: file:
MMapDirectory@/b/vin291f1/vol/vin291f1v3/idx/solr_index/test/data/index
lockFactory=org.apache.lucene.store.NativeFSLockFactory@169f6ad3 appears
both in delegate and in cache: cache=[_2omj.fnm, _2omg_Lucene50_0.doc,
........ _2omg.nvm],delegate=[write.lock, _1wuk.si, ........ segments_2b]
at
org.apache.lucene.store.NRTCachingDirectory.listAll(NRTCachingDirectory.java:103)
What does it mean?
I _think_ the error log is due to the NAS drive being disconnected before
shutting down Solr, but I need a Solr expect to confirm.
Unfortunately, I cannot find anything in solr.log files regarding this
because those files have rotated.
Thanks in advanced.
Steve
