I just tried to recreate your problem with a message that is 1 Mb big. While Log4View took a reasonable longer time to read it, in the end it worked fine. Could you try let Log4View load without interrupting and tell us your loading times? How many messages of that size do you have in a single log file?
yes, the log file would be helpful indeed. Our address is email@example.com, thank you for your help.
In the mean time you may also check if you encounter the same problem with our latest version 12.6.5.
