Created attachment 183848 [details] Test case to reproduce the issue. I have a program which using the java UNO api using Jodconverter with a Filter which does inserts in ODT documents. Combining the actions "insert another document and load styles from another document" with a insert TOC or update TOC action locks libreoffice on some documents (not all). The cpu of soffice.bin goes 100% and the jodconverter task timesouts. Debugging in java shows jodconverter waiting. The issue reproduces on libreoffice 7.2, 7.3, 7.4.3.2 (ubuntu) and 7.5 alpha from Nov 27*. It also reproduces on Debian 11 with similar versions including 7.5 alpha. While multiple factors need to be there, the problem seems to be close to the TOC. Removing the TOC insert or update makes the code work. Using a smaller files also makes the code work. I have a test case to show when the code is working and when the code is failing and multiple gdb stack traces. Which are attached. See below for indication on how to run the test case. Here is a sample gdb stack trace on 7.5 alpha (some stack traces are slightly different then this one where tweaking the test case). libreoffice7.5 (Nov 28) runfailing3 #0 0x00007fd00d0d71c6 in void

the test cases: 1/ Download the officepb.zip 2/ Download jodconverter cli 4.4 zip or tar: https://github.com/sbraconnier/jodconverter/releases/tag/v4.4.4 unzip it inside officepb.zip 3/ If you have jdk11 and libreoffice installed, you should be able to run ./runworking.sh or runfailing1.sh to reproduce the issue. Some debug should show where the code is. If there is no lock the program should end in less than 10 seconds. If not it will wait for the jodconverter timeout. If somebeody tries the test case and has a difficulty, I can help make it work. The issue looks similar to: https://bugs.documentfoundation.org/show_bug.cgi?id=152166 https://bugs.documentfoundation.org/show_bug.cgi?id=150138 https://bugs.documentfoundation.org/show_bug.cgi?id=151736 but I was not able to reproduce this in the writer manually.
