IceGridRegistry stops accepting connections

n2503vn2503v Alex MakarenkoOrganization: ACFR, University of SydneyProject: OrcaMember ✭✭✭
I run IceGridRegistry 3.0.0 on a Linux server and use its Locate and Admin interfaces. Periodically, about once a week, the registry stops accepting connections.

If I look at the process list on the server I can see a bunch of processes created in the last several hours. If I restart the registry everything works again for another week.

Does anyone else notice this? Is there any other way to debug this?

thanks, alex

    Hi Alex,

    Which Linux distribution do you use? I don't think you're seeing multiple processes here, it's probably the threads of the icegridregistry process.

    You could try to add network tracing (with Ice.Trace.Network=2) on the IceGrid registry and check the traces when it stops accepting new connections. But the best would be to attach to the IceGrid registry with the debugger when it stops responding and get a stack trace dump of all the IceGrid registry threads (let us know if you need more information on how to do this). If you attach the thread dump here on the forum, we'll take a look at it and check if there's anything wrong. Of course, a small example demonstrating the problem would also be fine but I suspect this might not be so easy to reproduce!

    Thanks,

    Benoit.

    Hi Benoit, sorry for a bit of a delay in replying.

    We use Debian 'testing'.

    ok, i can do it, if you tell me how.

    thanks, alex

    You need to find the pid of the registry (any of them will do). Then you do

    gdb - <pid>
    then
    thread all apply bt
    cut & paste the output. Or you can first run typescript, run the gdb commands and such and then exit. The output will be contained in a file called typescript.

    thanks matthew, will wait now for the condition to reoccur.

    So here it is. The registry ran exactly 7 days before going silent. First there's a list of all the threads. And then the traceback of from gdb.

    thanks for checking it out, alex

    Hi Alex,

    All the threads of the Ice server thread pool are stuck in calls to the C library and GCC library (following an exception raised by the TcpTransceiver.) This really looks like a compiler/libc problem to me. Which libc and compiler version do you use? Can you make sure that you have all the patch applied for your distribution?

    Cheers,
    Benoit.

    the compiler is from Debian 'testing', upgraded in the last couple of days:

    gcc (GCC) 4.0.3 20060128 (prerelease) (Debian 4.0.2-8)

    does ldd give reliable information on libc?

    $ ldd /opt/Ice-3.0.1/bin/icegridregistry
    linux-gate.so.1 => (0xffffe000)
    libIceGrid.so.30 => /opt/Ice-3.0.1/lib/libIceGrid.so.30 (0xb7d5c000)

    libdl.so.2 => /lib/tls/libdl.so.

    do you mean Ice and IceGrid patches? I haven't applied any. I can try.

    Sorry Benoit, I got a bit confused between different machines. Disregard the last email. I run a mix of Ice 3.0.0 and 3.0.1 between the server and the clients.

    The server runs IceGrid registry 3.0.0 and ldd reports this:

    $ ldd /opt/Ice-3.0.0/bin/icegridregistry
    libIceGrid.so.30 => /opt/Ice-3.0.0/lib/libIceGrid.so.30 (0x40017000)
    libIceStormService.so.30 => /opt/Ice-3.0.0/lib/libIceStormService.so.30 (0x401bc000)
    libGlacier2.so.30 => /opt/Ice-3.0.0/lib/libGlacier2.so.30 (0x4026e000)
    libFreeze.so.30 => /opt/Ice-3.0.0/lib/libFreeze.so.30 (0x402b0000)
    libIceBox.so.30 => /opt/Ice-3.0.0/lib/libIceBox.so.30 (0x4036a000)
    libIceXML.so.30 => /opt/Ice-3.0.0/lib/libIceXML.so.30 (0x40382000)
    libIce.so.30 => /opt/Ice-3.0.0/lib/libIce.so.30 (0x40395000)
    libIceUtil.so.30 => /opt/Ice-3.0.0/lib/libIceUtil.so.30 (0x4061f000)
    libpthread.so.0 => /lib/libpthread.so.0 (0x4066f000)
    libdb_cxx-4.3.so => /usr/lib/libdb_cxx-4.3.so (0x406c2000)
    libstdc++.so.6 => /usr/lib/libstdc++.so.6 (0x407b7000)
    libm.so.6 => /lib/libm.so.6 (0x40893000)
    libgcc_s.so.1 => /lib/libgcc_s.so.1 (0x408b8000)
    libc.so.6 => /lib/libc.so.6 (0x408c4000)
    libexpat.so.1 => /usr/lib/libexpat.so.1 (0x409dd000)

    libdl.so.2 => /lib/libdl.so.2 (0x40a0e000)
    /lib/ld-linux.so.2 (0x40000000)

    the compiler is slightly older, but should be new enough:

    gcc (GCC) 4.0.3 20051201 (prerelease) (Debian 4.0.2-5)
  • n2503vn2503v Alex MakarenkoOrganization: ACFR, University of SydneyProject: OrcaMember ✭✭✭
    Benoit,

    turns out the server was running on kernel 2.4.x-SMP. That might've led to some lib confusion.

    I upgraded to kernel 2.6.15-SMP and compiled Ice-3.0.1 with gcc 4.0.3. hopefully, the problem will go away, i'll let you know.

    alex
  • n2503vn2503v Alex MakarenkoOrganization: ACFR, University of SydneyProject: OrcaMember ✭✭✭
    Just to close this issue... After upgrading to the new kernel and everything that comes with it, the registry has been running continuously for over a month now with no problems.

    thanks for your help, alex

    Hi Alex,

    Thanks for the info, I'm glad it works fine now!

    Cheers,
    Benoit.
