Downloaded and installed the category module according to the included documentation. Went to admin/modules to enable the module, and immediately received an error. Output to screen was:
--------------
Server Error
The following error occurred:
[code=SERVER_RESPONSE_CLOSE] The server closed the connection while reading the response. Contact your system administrator.
Please contact the administrator.

Have been unable to resolve or find further information which relates.

I've had the same issue on a server hosted by someone else. It is probably due to Drupal not waiting long enough for feedback from the filesystem when it scans for (new) modules. Since category contains a directory with quite a few subdirs this is likely to cause this error. I have removed category completely and switched back to taxonomy because of other problems with integration between category and other non-core modules.

Hope this helps,
Eric

I'm under impression, that this was only just related to the size of Category package, interfering with core and settings of the server or something. Getting errors prior to enabling a module (other than parse errors on the code files) is most probably not a problem of that module.

Now, 4.7.x is not supported anymore, and 2.5 years passed in silence here - so closing this one.
