  • 1.  SockAdapter generates many core files

    Posted Nov 30, 2019 07:47 AM
    Hi!

    I have a problem with csampmux (SockAdapter). After restarting the AutoSys envieronment (CCS, Sheduler, WCC, etc), all components seems to be working in normal mode. But csampmux begins to create core.* files in $AUTOUSER. This core files occupy all free disk space. If I restart AutoSys envieronment again, problem is gone.
    I checked core files with gdb utility, but all, that I found:
    Core was generated by `/opt/CA/SharedComponents/Csam/SockAdapter/bin/csampmuxf'.
    Program terminated with signal 6, Aborted.
    The same time, when csampmux generates core file, it writes next lines to CA/SharedComponents/Csam/SockAdapter/log/

    My OS version is Red Hat Enterprise Linux Server release 6.10 (Santiago). AutoSys version is 11.3.6.919.

    Thanks for the help.

    Hey Bohdan,
    I think this issue related to IPV6 (cannot create listener on port [7163] for address family IPv6: 97)

    Try going  to the hosts file (on linux usually under /etc/hosts) // in windows somewhere under windows dir ..

    Add "#" before the line having the localhost6 in it like this :

    ​#::1 localhost localhost.localdomain localhost6 localhost6.localdomain6

    after wards leave the session and try restarting the service
    Hope it helps ,
    Yoni

    Thanks for your reply.

    I've checked /etc/host settings, IP v6 localhost line is turned off with #.

    My issue appears during next steps:
    ​- stopping all CA services
    - patching RedHat 6 and rebooting
    - starting all CA services in reverse order
    After this core files appear.
    But if I make previous steps again (without reboot):
    ​- stopping all CA services
    - starting all CA services in reverse order
    Core files will not appear.

    This will not be a problem to restart CA services twice, but I have no such possibility on weekends, when automatic patch management performs.
    I also have test CA envieronment on the server with RedHat 7 and the problem does not occur on that server.
