Something strange happened, with no error what-so-ever. Ran a taxwriter in parallel with a IndexWriter, but because the indexReader was NearRealTime, i reopened taxwriter and refreshed the taxreader every 3min.
day one, OK day two, OK day tree, no more indexing, results were only from the previous days day four, manually restarted the entire app (readers and writers and everything), the only thing that changed was that it started to index from then on. At the suggestion of Shay, I replaced the reopening of taxwriter with only a commit(); should i be in the clear now? any sugestions of what to look for or to replicate/debug the problem?
