B4J Question App crash EXCEPTION_ACCESS_VIOLATION

[madru]

Hello Community,

I have a big problem and can't find a solution

I have an app at a customer site running (connect to MySQL-DB via jRDC), it has been running for weeks without any problems, but today it crashed.
There is no exception that I catched in B4J; instead, a log is written by the VM. I've been trying to recreate the misbehavior for hours now, but unfortunately without success.

The modules used in this are the following:

• B4XCollections
• B4XPreferencesDialo
• B4XTable
• ByteConverter
• jB4XEncryption
• jCore
• jFX
• jOkHttpUtils2
• jPOI
• jRandomAccessFile
• jShell
• jStringUtils
• KeyValueStore
• xCustomListView
• XUIViews
• ZoomImageView

The dump is attached if anyone wants to take a look at it

As I understand it, something is going wrong with SQLite but SQLite is not used directly; I think only in B4XTable?

Any help is welcome.

THX

Guido

B4XTable is using SQLite. This is a low level crash so not simple to debug.

You can try to update the native library: https://www.b4x.com/android/forum/threads/sqlite-jdbc-library-version-updates.133792/#content

I don't know whether it will change anything or not.

#AdditionalJar: sqlite-jdbc-3.45.3.0
