Code:

[2014-02-14 18:23:55.255] Database is at level 13
[2014-02-14 18:23:55.267] DEBUG: Will apply sql:
ALTER TABLE block DROP COLUMN IF EXISTS index
[2014-02-14 18:26:26.984] DEBUG: Will apply sql:
ALTER TABLE transaction DROP COLUMN IF EXISTS index
[2014-02-14 18:33:32.807] Updated database is at level 15

Didn't the additional indexes help?

Question: Is it possible to re-use the nxt_db directory when upgrading from 0.7.4 to 0.7.5 without downloading the whole blockchain again?

Raspis do have a tough time doing that, crashes 1-3 each time, must be restarted, takes severla hours in total...

I don't have problems downloading the whole blockchain with my RPi (not overclocked), no crashes, no restarts. It takes hours... hmm yes maybe 1-2 hours, but you don't have to do that on every update. The last time i did was when i switched to 0.7.2. From then i always copied the db to my new nxt-folder.

No, no.

It does not. Just overclock it at medium level. Works like a charm for me.

And yes, you can re-use the db of 0.7.4.

In fact the nxt.log above shows the migration from 0.7.4 to 0.7.5.

I didn't overclock mine. To what CPU-rate did you overclock it? Do you use some kind of cooling? My RPi is just in an ordinary plastic-case, no cooling at all...
