Thank you for your reply.
I am already using compound file format, and the minMergeDocs is already
increased to 50.
As my understanding and observation, files are compounded at the end of
indexing. The error happens when indexing, so compound file format
should not matter.

Increase the minMergeDocs and use the compact file format when creating your
index.
