The logger calls those functions when a message is received or sent:

   fopen/fseek/fprintf/fclose

Those are standard libc function, fclose might be syncing file to disk which is
a legitimate use. I strongly doubt that the logger is responsible for making
btrfs unstable, but I would have a look at traces from the logger (could be
debug traces using TPL_DEBUG=all, or straces showing abuse of sync system call)
if you take the time to provide them. Also, mentioning logger version and step
to reproduce is important in bug reports, please consider providing those for
any further reports on any projects.
