Zone.exe crash when receiving items

On a fresh made server[Rev2065] and fresh DB[Rev2027].
Titanium client.
Whenever a player loots an item zone.exe crashes. Possible causes from logs...

Zone.exe also crashes when receiving items from npc(quest reward), but no error appears in the log when this occurs.

If a character has a gm flag(#gm on), zone.exe does NOT crash in the above scenarios.
This happens in all zones and with all types of items.

Edit-- When logging back in after the crash the item that was being looted/received is on the cursor.
Edit2-- Other errors

The easiest way to track down a 100% repeatable problem is to add debugging information to zone.exe, attach the debugger to the zone you are in, and cause a crash. From there you can look at the call stack and see exactly what is going on.

Sounds like you need to source in some SQL updates, I bet if you turn on your debugger you will see it is having troubles with SELECT alt_currency or some other recently added field.

Make sure to source in all the sql updates from 2004 to 2062 up from /trunk/EqEmuServer/utils/sql/svn/

This can help resolve zone crash issues from items.

Thanks for the replies, all looks good now.
It appears to have been one of the updates from /trunk/EqEmuServer/utils/sql/svn/, probably 2024(req) or 2057(req). Most of the others, including alt_currency, failed due to duplicate entries.
My question from this is, how do you know which updates are not applied yet when starting a new database? My thought was that the newest db would have the newest updates.
Or is it that since my Db was Rev2027 and server was Rev2065 then I needed to apply any updates in /trunk/EqEmuServer/utils/sql/svn/ that were 2027+? (e.g., 2057, 2058, 2062...) [This actually makes sense and can't believe I didn't realize it until someone pointed it out.]

Also, thanks for that debugger tip. Will be useful in the future I'm sure, once I learn how to use it. )
