I don't remember why there is abort() in XLogFileOpen just before
appropriate elog(STOP) there - I'll remove it in few moments, - but
it's already obvious why open failed: there is no file with checkpoint
record pointed by pg_control - data/pg_xlog/000000000000002F.
So, the question is who removed this file - PG or Linux?
Ryan, do you have postmaster' log before crash (where MoveOfflineLogs
reports WAL files to be deleted) and/or some logs from Linux' startup?
And meanwhile I'll take a look arround MoveOfflineLogs...
