Hello,

This error occurs quite randomly, often after a few minutes of use when I open a new file. After that the process just crash and i have to relaunch.

**Fatal:src/cache.c:509:Cache_free: could not destroy w_lock!**

Oops! HTTPDirFS crashed! :(

Which distro are you using, and which version of that distro are you using? Could I potentially access the server you are using?

This is going to a fun one...

Hello,

Unfortunately, the server contains private documents, so I cannot share it. The server is running Ubuntu 23.04, Kernel 6.2.0-39-generic. However, I can test the issue on an Arch or Debian system if needed.

Additionally, I’m open to recompiling the code with debug traces if that would be helpful. For context, the cache is written to an XFS filesystem (though I’m not sure if that detail is relevant).

I’ve reviewed #91 and #126. It’s certainly not fun, but would it be possible to handle these errors as non-fatal for the application? Specifically, I’m wondering if it’s necessary to crash the entire process due to a failure in handling a cache file.
