DBENG50.exe crash (sybase client db crash)

[Former Member]

Hi all,

power builder 10.0 application crashes in middle and gives the "dbeng50.exe" has stopped working with exception code "c0000005", after which we have to close the entire application and restart the application. can you help in finding the issue.

This issue started to come after migrating the application to a 64 bit operating system(window 2008 R2). This problem does not come in windows xp machine.

This was problem was not happening even in windows 7 32 bit operating system.

when i took a windows crash dump after the application crash, it was pointing to these below dll

wow64.dll wow64cpu.dll wow64win.dll.

i know these dll are used for running 32 bit application on 64 bit Operating system. Could anyone shed some light on this.

thank in advance...

In my experience dbeng50.exe is unstable on Windows 7. It was never tested on modern Windows operating systems, and it is not supported. Migration to SQL Anywhere 16 is highly recommended... or stick with Windows XP.

...or choose SQL Anywhere 9.0.2 which is the latest version which can run a v5.5 database without migrating/reloading it - and late v9.0.2 EBFs have been tested with Windows 7 and Server 2008 R2, IIRC.
