I'm getting a segmentation fault on a large index (15GB). I'm running
ferret 0.11.4 on OpenSuSE 10.2 with ruby 1.8.6. The segmentation
fault appeared after I optimized the index, see further below for the
error message I got before that. Ferret works perfectly on other (smaller)
indexes.
Is this a known issue, and if so, is there a workaround?
