The issue can be identified by the following message in the log file:

Error - number not found at end

Above message is printed to VisualVM's log when GC root computation is running.
This can happen in heap dumps, which uses PRIVATE map mode and are sufficiently large to use chained MappedByteBuffers for NBProfiler___.map file.

VisualVM 2.1.10
