4.2a beta 2 Indexer Crash - Unhandled exception: The database disk image is malformed

Mark Barnes

99.9% sure my problem is not caused by overheating. More likely, perhaps, is that I was indexing, then paused, then because the indexing didn't seem to stop, I unpaused then paused again, then triggered a download. Almost immediately I then got this crash.

Looks like the Indexer got mixed up. Just restart L4 & it should resume downloading & indexing
