Hot replacement unloads the old library while an asynchronous completion callback still points into its code.
Estimated field mix
A package publish selects the native binary by platform name but ignores CPU features and libc compatibility.
Estimated field mix
The adapter assumes one read fills the requested buffer and silently truncates a generated manifest after an injected short read.
Estimated field mix
A crash between truncation and write leaves the agent configuration empty.
Estimated field mix
Every interrupted call is retried automatically, so a cancelled operation keeps waiting after shutdown begins.
Estimated field mix
An NTP correction moves wall time backwards and extends a file-processing deadline by several minutes.
Estimated field mix
One editor save produces create, rename, and modify events; the agent processes the same file three times and misses changes after queue overflow.
Estimated field mix
Recursive scanning opens every subdirectory before closing any, exhausting the process descriptor limit.
Estimated field mix
A path is validated under the inbox, then a directory is replaced with a symlink before open, escaping the allowed root.
Estimated field mix
The Windows fixture cannot provide the same directory-flush guarantee as the Unix adapter, but both report durable replacement.
Estimated field mix
A crash leaves temporary files beside the destination; startup cannot tell whether they are incomplete writes or a replacement ready to finish.
Estimated field mix
An installer manifest requests administrator access even though the agent operates only inside a user-selected directory.
