There is a known problem in "LinguaPlone".
Usually, it is described by: Zope takes almost all CPU time.
Maybe, what you see is an instance of thos bug.

Alternatively, something may be wrong with "getTranslations".

Obviously, the problem occurs still in "BaseRequest.traverse".
This means, "manage_FTPlist" has not even started and you
do not have an FTP problem. But a problem with the folder
you try to FTP into. That translations are maintained in
references is a bit suspicious.


Check whether the "LinguaPlone" bug hits you.


If this is not the case, then debugging "getTranslations"
is probably the most efficient way to locate the problem.

Stays the part above (maybe partially) accross several
"DeadlockDebugger" invocations (or changes the tail of your

In this case, there would seem to be some infinite loop caused
by the AT "ReferenceEngine" (I like it).

 


As you supposed the tail changes if I invoke DeadlockDebugger several times.
Here are 3 more examples besides the one I sent before:

Stays the part above (maybe partially) accross several
"DeadlockDebugger" invocations (or changes the tail of your
traceback continously)?

In this case, there would seem to be some infinite loop caused
by the AT "ReferenceEngine" (I like it).

[Zope] ftp server deadlocking zope with DeadlockDebugger

2006-05-05 Thread Michael Kaplan 

Hello,

about 2 weeks ago I reported about my ftp-problem
(see attached listing).

In the meantime I installed DeadlockDebugger-1.0.tgz
from http://www.zope.org/Members/nuxeo/Products/DeadlockDebugger

Here is the output of this program for the thread that seems 
to be responsible for the deadlock. This happens when I open

a ftp connection to the server, cd to a directory and launch
the 'ls'-command:

I have a problem with the Medusa FTP server deadlocking Zope completely.

I'm using Zope 2.8.5-final, python 2.3.5, sunos5 with standard port
settings and port-base 1500, e.g.

ZServer.HTTPServer.zhttp_server (Port: 9580)
ZServer.FTPServer.FTPServer (Port: 9521)

I can connect to the ftp server



ftp localhost 9521
 


Connected to localhost.
220  FTP server (Medusa Async V24763 [experimental]) ready.
Name (localhost:root): ***
331 Password required.
Password: **
230 Login successful.
ftp> cd dir
250 CWD command successful.

The standard ftp commands *cd*, *lcd*, *put* and *get* work fine.
 
But if I try to use *ls*, *dir* or *mkdir* Zope seems to arrive in an

infinite loop blocks one cpu completely and has to be restarted.
