Hi, trying DigitalOcean for Solr, everything seems well, except sometimes I
see these errors:

Solr version is 4.8.1, on Ubuntu Linux. We have 2 nodes, one run 2 shards
and another 2 replicas.
Errors happen during indexing process. Does it require some
tweaks/optimizations? I have no idea where to look to fix this. Any
suggestions are welcome.
Thank you,
Alex
