<p>Hi,</p>
<p><br>
</p>
<p>Thanks for using the PRF form. Can you attach a debugger and see
where the server is looping exactly?</p>
<p><br>
</p>
Best regards,<br>

<br>
<br>
TAO VERSION: 2.4.1<br>
ACE VERSION: 6.4.1<br>
<br>
HOST MACHINE and OPERATING SYSTEM:<br>
Debian 8 (Jessie)<br>
<br>
COMPILER: g++ (Debian 4.9.2-10) 4.9.2 <br>
<br>
<br>
DOES THE PROBLEM AFFECT:<br>
EXECUTION? YES<br>
<br>
<br>
SYNOPSIS:<br>
CORBA service after some time working idle (1 night) can't
process requests. (migration result)<br>
<br>
DESCRIPTION:<br>
At the beginning I want to highlight that we use version of
ACE-TAO compiled with option "threads 0". The problem started to
happen with many services after migration to newest version of
ACE TAO and operating system. Up to now the system worked stable
on version 1.2.1/5.2.1 (linux lenny).<br>
<br>
How it works:<br>
Server application registers CORBA service in NamingService.<br>
If a client connects shortly after start of the server<br>
then the server works fine: the server process request properly.<br>
<br>
After some time (for example 1 night) a client connects to the
Server, but<br>
when the client tries to use service then the server hangs up
and use 100% of a processor.<br>
Client is blocked by the server until the server is killed.
Debugging, we found out that the problem is somewhere inside
CORBA invocation. Very unclear are debug information seen during
loading adatp3-services.svc, but we are not able fully interpret
this issue.<br>
<br>
The services is run with the following ORBParameters:<br>
-ORBDottedDecimalAddresses 1<br>
-ORBDebug -ORBDebugLevel 10 -ORBVerboseLogging 2
-ORBInitRef NameService=corbaloc::server:30033/NameService<br>
-ORBSvcConf adatp3-services.svc<br>
<br>
and adatp3-services.svc:<br>

tionCacheLock null"<br>
static Server_Strategy_Factory "-ORBAllowReactivationOfSystemids

static Client_Strategy_Factory "-ORBTransportMuxStrategy

REPEAT BY:<br>
Every Time<br>

TAO LOG:<br>
<br>
The Log of the server is showed below. The log is divided into
parts:<br>
<br>
[Start Server]<br>
[Client connect to Server after short time]<br>
[Client is connecting after some time]<br>
