I have a Helios Acer Predator 300 computer (Predator-G3-572) and recently did a hardware update, installing a 1Tb SSD. This greatly improved performance, allowing for more machine efficiency, both for work since I am a developer and for games.
However, I started to notice a problem, now the system does not seem to work properly anymore, recording a syslog file of exorbitant sizes (the last file I deleted, was about 50GB).
UPDATE:
I believe the problem may be the logrotate. In analysis, I went to check if the logrotate program was working properly. At first all settings are normal, but the syslog file is now larger than 1 MB, while it should rotate with 100 KB.
Example, one-day log:

Ele inclui um gerenciador de biblioteca, conversor de formatos, conversor de feeds de notícias em e-book assim como recursos de sincronização de leitores de e-book.#012#012Calibre é principalmente um programa catalogador de e-books. Ele gerencia sua coleção de e-books. Ele foi desenhado ao redor do conceito de livro lógico, isto é, uma única entrada no banco de dados pode corresponder a e-books em vários formatos. Ele também dá suporte a conversão de dúzias de diferentes formatos de e-books para LRF e EPUB. Uma interface gráfica para o software de conversão pode ser facilmente acessada simplesmente clicando no botão "Converter e-books".#012#012Os formatos de entrada para os quais há suporte são: MOBI, LIT, PRC, EPUB, ODT, HTML, CBR, CBZ, RTF, TXT, PDF e LRS.#012#012Calibre possui um desenho modular de driver de dispositivo que torna fácil adicionar suporte para diferentes dispositivos de leitura eletrônica. No momento, ele possui suporte para SONY PRS 500/505/700 e iPhone (com o software "stanza" de leitura). A sincronização dá suporte à atualização de metadados no dispositivo a partir de metadados na biblioteca e à criação de coleções no dispositivo baseada em etiquetas definidas na visualização da biblioteca. Se um livro possui mais de um formato disponível, o calibre escolhe automaticamente o melhor formato quando for enviá-lo para o dispositivo.#012#012O calibre pode automaticamente obter notícias de vários sites web e feeds RSS, formatar as notícias em um e-book e carregá-lo em um dispositivo conectado. Há suporte para geração de e-books LRF/EPUB. Os e-books incluem as versões *completas* dos artigos, não apenas os sumários.#012#012O calibre também possui um visualizador embutido de e-book que pode exibir todos os principais formatos de e-book.#012source-00: calibre#012source-id-00: calibre;3.21.0+dfsg-1build1;all;ubuntu-bionic-universe#012url{homepage}: http://calibre-ebook.com#012license: LicenseRef-free=https://www.ubuntu.com/about/about-ubuntu/licensing#012license-is-free: yes#012management-plugin: packagekit#012origin: ubuntu-bionic-universe#012origin-appstream: ubuntu-bionic-universe#012reviews: 0#012provides: 0#012install-date: 1#012size-installed: unknowable#012size-download: 24,7 MB#012category: Graphics#012category: Viewer#012{GnomeSoftware::Creator}: appstream#012{appstream::source-file}: /usr/share/applications/calibre-lrfviewer.desktop

In reviewing your
syslog, I didn't have to go to far to find a number of issues. I'll document some of them in the form of this answer, as there's too much to place into comments.Note: Place all output as an edit to your question, not into comments, please.
CPUs overheating mce: CPU6: Package temperature above threshold, cpu clock throttled (total events = 6796)
MCE is machine check error. Generally not a good thing to see. Is it very dirty/dusty?
Have you overclocked the CPU/RAM in this computer?
GNOME Shell crash
ls -al ~/.local/share/gnome-shell/extensionsls -al /usr/share/gnome-shell/extensionsdrawnio app
font issue
snap listYou could try installing Stacer from the Ubuntu Sotware Center.
The system automatically generates many sys log files but some general housekeeping is always a good thing. The sys log files can be useful in other circumstances.
Select the option System Cleaner regularly to keep things trim and tight.
