Hi, Thanks for the report! It might prove helpful to know the following: 1. Does Zope hang when you access the management interface using http://path/to/zope/manage_main or ftp? 2. Does Zope hang if you run in single threaded mode (z2.py -t 1)? 3. Are you using the default NUMBER_OF_THREADS (4)? 4. Are you using any database adaptors and, if so, which versions? 5. Is the hanging more or less frequent in Zope 2.1.6 than in 2.1.4? 6. What method of access (HTTP/PCGI/FCGI) do you use for the management interface? Is this the same protocol you use for the rest of the site? 7. Are you using a binary distribution of Zope, or have you compiled from source? Ditto for python. 8. Can you cause Zope to hang by refreshing the page a number of times in quick succession, or by stopping the request and then reloading? You mentioned that the hanging occurs when an error occurs. Are you referring to a Zope error, or an error which is logged or displayed on the console? A traceback or listing of the error might prove useful. Some of these might just be shots in the dark, but the more information we can gather, the better! Some also might not be practical for you to try out (like running Zope single-threaded, if this is a production server). Tres Seaver suggested this morning that we move discussions like this to a purpose-built Wiki at zope.org, but as that's now, I suggest we keep the discussion going on the list until the Wiki can be used. hth, and thanks! -- Marcus

Hi,
I've noticed something here, but it doesn't seem thread related since all zope hangs.
from time to time (seems to be random), when using the management interface, zope completely hangs when using IE5 under NT4SP5. With IE4 on the same machine (before the update) or Netscape 4.72 under Linux (same machine in dual boot) there's no problem at all. It seems (not sure) the hang comes when an error occurs, and error often occur when you begin with zope...
when it hangs I can't connect to zope from any workstation here, even trying to access a different page, outside the management interface.
Tested with 2.1.4 and 2.1.6 under SparcLinux (RedHat 4.2, kernel 2.0.35, libc-5.3.12, python 1.5.2), and we don't suffer seem to suffer from memory leaks.
hope this helps to solve the problems.
