--- Comment #16 from Frank franksauer@cox.net --- In working with Bradley from Logos, we were able to come up with a work around to get the indexer to complete. The issue appears to be with the AutoComplete database building. The indexer does not seem to actually ever begin indexing and hangs on the AutoComplete database structure which proceeds the actual indexing when the indexer starts.
The issue is not on Windows and is limited to Wine. For comparison my database file in the Logs wine install was nowhere near the fully completed database file from my Windows installation, which was over 150 MB. So something in the wine install is not allowing the AutoComplete Database to build, thus allowing the indexer to begin indexing the resources upon completion of said database.
The workaround that I used was to copy the two files located in the AutoComplete directory from my Windows install to the Wine install - this allowed the indexer to move on and fully index the system without crashing. I had my wine set to Win10 and it indexed without issue. It also allowed greater use of the CPU which was limited to the low teens % and after copying the files over allowed the CPU to uses as much as needed, which allowed the RAM use to reach nowhere near the rate without copying the files over.
