LOG4OM is crashing more often

[9k2hn]

I'm using Ver 2.34.0.0 and mariadb everything looks ok but when I tried to perform a backup after freezing for a few minutes Log4OM crashes, and even some times when I search old qso marked with requested to be uploaded to HRD it crashed again.

Here a copy of the log

Any idea?

Says you have a memory issue

[9k2hn]

But sure this is not the issue I have 32GB of Ram, maybe due to Log4OM limitation because it is 32bit?

Could be a faulty memory strip, do the tests for that

Also try a fresh install - Uninstall from Add and remove programs - fresh download and install

Sorry for the delay, I'm using mariaDB, what is the best way to backup and restore? including log4om setting

[9k2hn]

Wehn I pasted the error log into Gemini I got this

Possible Causes and Solutions:

Large Logbook: If you have a very large logbook with many QSOs and confirmations, it might exceed the memory capacity of your software or system.
Solution: Consider increasing your computer's RAM or using a 64-bit version of your logging software if available. You could also try splitting your logbook into smaller files.

So is there any chance to upgrade Log4OM to 64bit?

Hello Hamad.

Sorry for the delay, I'm using mariaDB, what is the best way to backup and restore? including log4om setting

Log4OMv2 configuration is stored in file located here:
C:\Users\<your-username>\AppData\Roaming\Log4OM\user\config.json
Alternatively, you may save whole C:\Users\<your-username>\AppData\Roaming\Log4OM directory.
In my W10 system it is 699Mb big.

In regard backup of MariaDB database, see User Guide,
chapter "Installing MySQL-8.0.20 with Log4OM Version 2",
page 266, below last picture.

Hope this helps.
