i am testing word files covert to pdfs, all word files are in Chinese with 100+pages, and this problem occurs very frequently.
\nthis is my .env file:
\n# base\nAPI_TIMEOUT=3600s\n# libreoffice\nLIBREOFFICE_MAX_QUEUE_SIZE=1\nLIBREOFFICE_RESTART_AFTER=1\nLIBREOFFICE_AUTO_START=true\nLIBREOFFICE_START_TIMEOUT=60s\nthis is my docker compose file:
\nversion: '3.8'\n\nservices:\n gotenberg1:\n image: gotenberg/gotenberg:8.23.1\n container_name: gotenberg-instance-1\n environment:\n - TZ=Asia/Shanghai\n ports:\n - \"8094:3000\"\n volumes:\n - ./fonts:/usr/local/share/fonts\n env_file:\n - .env\n restart: unless-stoppedI set API_TIMEOUT=60s or 600s or 3600s , they are all can't complete the task normally, is my settings wrong?
\nuse docker stats see the cpus is using 103%, memory using 240M, and after each task ends abnormally, the CPU usage remains at 100%+, I dont know why? i am in China, if some package url timeout ?
\nand i search google says mount fonts to docker, but problems remain.
\nand i set Load Balancin , but problems remain.
Thinks!

Hello @finch-xu, LibreOffice struggles with « large » files, not sure if I can do anything alas! Maybe try to increase the CPU/Memory of your instance? |

I try to solve the problem all day, and I found some clues, those word files are all in Chinese, documents written by different people on different computers, has may different fonts, I build a new docker image with my windows fonts and other debain apt depends, and resolved a batch of document issues, But there are still many documents that have problems. |

Thanks for the investigation @finch-xu! Very interesting, it’s not the first time this issue arise, but I always assumed it was because of the file size, not the fonts! But now that you’ve said it, it makes sense that word files, usually coming from many sources, may contain fonts that are not available in the image. I’ll update the documentation with your findings! |

Yes, I have searched for the same problem in the past issuses. None of them could solve my problem, but this error is rather broad and imprecise, so if someone else encounters the same error, it may be caused by other problems. |
