Hi,

I am attempting to build the C client on debian lenny.

autoconf, configure, make and make install all appear to work cleanly.

I ran:

autoreconf -if
./configure
make
make install
make run-check

However, the unit tests fail:

$ make run-check
make  zktest-st zktest-mt

This appears to come from tests/TestClient.cc - but beyond that, it is
hard
to identify which equality assertion failed.

Help !

Hi,
$subject occurs in simple version test.This test failure says repository
does not support versioning

But I have set the following to true

OPTION_VERSIONING_SUPPORTED = true
OPTION_SIMPLE_VERSIONING_SUPPORTED = true

It will be really great if anyone can help me to solve this problem

Thanks for response.

The first server on I install tomcat 5.5.28 is win2003 server and after I 
install jboss on win2008 server .
All server have  32bit SO and i don't have a firewall . I disenable all 
firewall, all antivirus. 

I suppose that two different errors regard different JVM and/or
Application 
server (first Tomct 5.5.28 on win2003 and after Jboss4.2.3GA on win2008)
At any rate i have now only log by Tomcat 5.5.28 under win2003:

The log is:

Now i use jboss so the error that i have on win2008 server is :

010-05-17 12:53:24,112 ERROR [org.apache.tomcat.util.net.JIoEndpoint]

But don't have a intere log file.
May be IPV6? I don't disinstall this protocol becuse is important on
win2008, 
but i hve clent that use IPV4.
Have you  n idea?
How can resolve  problem.
Plese is imporatnt for me?

Best regards
Agostino

If I'm reading the stack trace correctly, the listening socket is
being
closed shortly after being opened.  Do you have a firewall that is
blocking the port perhaps?

If you start a completely new log file, what messages appear before
the
error appears?

Thanks 

The question started in 
http://mail-archives.apache.org/mod_m...005.mbox/thread?3
   
on same thread.

Now i have reduce the number of user (about 50 user simultanely) on a   
win2003 ED quad processor with 8GB bram (I have tomcat 5.5.28, jdk.1.6.16,
IIS 
(with certificate instaled) on port 80 that redirect  request from port 80
to 
8080 tomcat connector   server. Besides https request are directly managed
from 
second connector, on port 443 of tomcat.)

So  the error referred, sometime occours. In particular i have noted that
this 
error rise when a lot user make  login in the application (  in a few
second).
Probably  this may be depend from a lot tcp/ip connection, but, this using

netstat -na not appear.
May be i must increase the number on maxTcpConnection on win2003 server
and/or 
reduce tcpDelay.
Please give me a help to resolve the problem.
What tool i can use for investigate who cause socket close.

The part of default server.xml of tomcat  that i have change(2 connector 
configuration an docbase) is :


.......

    <!-- Define a non-SSL HTTP/1.1 Connector on port 8080 -->
    <Connector
port="8080"    maxHttpHeaderSize="8192"
               maxThreads="350" minSpareThreads="50" maxSpareThreads="100"
