Violation exception in module nwn2server.exe at 001b:005d58de.
Read from location 00000004 caused an access violation.

This has been the only crash I've gotten in 1.13 since I patched and I get it about once an hour looking at the time between error_logs.

We have some stability issues since 1.13. Maybe due to disabled xp_bugix.
When can we expect an update? Smile

Skywing isn't going to update until the hotfix in 2 weeks, but I'm looking to update before then and might have an "Unofficial" version if I can quickly locate the right offsets to update.

That requires me to install 1.12 to do a code comparison (Which I havn't done yet). LAAAAAZY Smile

Again, I echo everyones thanks. Take your time. I will wait to update, since your dll helped alot, and there are other issues with the patch too.

New beta release (for 1.12) - http://www.nynaeve.net/Skywing/nwn2/xp_bugfix_beta_009/xp_bugfix.zip

This has the following new fixes:

- Fix for lack of handling for bad zlib data + lack of validation on compressed data chunk length field (should finally put a stake in that 005cd7cc crash, another path that could have lead to that).
- Fix for a crash resulting from a player without a game object associated sending an Inventory.6 (Unequip?) message (004f7e27)
- Fix for a crash resulting from a wrong object type used with ActionExchangeItem (004e7a49)
- Fix for a crash when a creature without an item container attempts to acquire an item (004a1586)

I don't have test cases for all of these, so please be careful when trying the new build. Let me know if you run into problems.

Once again, this build is for 1.12, and not 1.13, which is still awaiting a hotfix.

I have posted a beta release of xp_bugfix 0.0.9 for 1.0.13.1409 (the "1.13 hotfix"). This build does not work on the original 1.13 patch, or the 1.12 patch.

If you are using 1.12, you will have to get the build stamped for 1.12.
If you are using the 1.13 original patch, you will need to upgrade to the hotfix (now on the updater as far as I know), and then get the build stamped for 1.13.

The 1.0.13.1409 build of xp_bugfix 0.0.9 beta can be had here:

Thank you VERY much for your speed and dedication.

Fixed a bug with the 0.0.9 beta that may manifest itself as new character creation hanging, along with the following log message in xp_bugfix.txt:

LogUncompress1Fix: Avoided crash due to invalid
compressed data.

I have rebuilt both the 1.0.12.1295 and 1.0.13.1409 binaries to fix this. (This is specific to 0.0.9 and was not present in 0.0.8 or below.)

New builds should identify themselves as 0.0.9b2 in the xp_bugfix.txt log at startup. Additionally, both the 1.0.12.1295 and 1.0.13.1409 builds now write a log message to xp_bugfix.txt at startup that identifes which NWN2 version they were built against, so you can make sure that you grabbed the correct .dll.

Posted 0.0.9b3 for 1.0.12.1295 and 1.0.13.1409, which fixes a null dereference when a CItemRepository contained an object id that did not resolve. (There likely needs to be a master check in ~CNWSItem to verify that the deleting item does not exist in any item repositories.) This is a new fix and is not a regression.

LOL That was fast! AMAZING!

Yes, indeed.

Thanks again.

This is good news. I'm glad someone has been able to address the 100% freeze issue. I was able to track down the code, but wasn't able to identify a fix.

good work!

I am going to call the 0.0.9b3 builds production builds, as I am not aware of any further issues being discovered with these builds.

A source drop will be forthcoming eventually. (The high quality stock Windows SVN client managed to eat my checkout when I attempted to merge xp_bugfix and xp_srvadmin to virusman's svn, so I am going to hold off until I have more patience for dealing with buggy source control systems.)

As a side note, most of the fixes in xp_bugfix would not have been possible without crash dumps from nwn2server. Thus, while not required, I would strongly encourage switching to my build of the NWNX4 core that supports writing crash dumps (see this thread). If you would like to see support for crash dumps in the stock NWNX4 build for purposes of a shot at seeing server crashes you see fixed, feel free to let Papillon know that you're interested in that seeing that feature accepted into the mainline code base.

(If you do get a server crash, a crash dump is much more useful to me in understanding the underlying NWN2 bug than simply the error logs, though the error logs are better than nothing.)

Has anyone observed a line as follows in their xp_bugfix.txt log while using the 0.0.9b3 release against nwn2server 1.0.13.1409?

Why is it that this nice plugin is not in the download section of the web?
