Crashes due to Access Violation

[Jan-Enneking]

Hello everyone,

While working with cadwork 30, I frequently encounter crashes on my computer that seem to coincide with Firebird crashes every time.

Unfortunately, the manufacturer has never encountered this issue with any other customer, and we are currently at a loss. It worked flawlessly on this machine for about six months, but now the possible runtime varies from just a few minutes to several hours.

The operating system is Windows 11. We recently performed a fresh installation, and the only software installed is cadwork with Firebird, Office, and a browser.

Where else could I look for clues, or what might be causing the issue?

The messages in the firebird.log always look like this, and the folder is named FB25, so it’s presumably version 2.5. The version comes bundled with the software, so I can’t upgrade it myself.

First, 2.5 in very old and not supported version, sorry.

Next, please, specify exact Firebird version - you may look for it at file version of any binary, such as fbserver.exe or fbclient.dll.

Next, we need full memory dump to analyze exact reason of a crash.

You may use WER, or ProcDump to produce it.

PS I moved firebird.log content into spoiler to make description a bit easy to read.
