Cant backup Suse client server

Hello,

I need help how to backup client Suse server. Backups were ok in past but now about one Month is not possible to backup it. Master and client are the same version of NetBackup 6.5.6 , connection seems to be ok, bptestbpcd ok, vnetd ok. All other clients server with same configuration run ok in this backup environment. Whole environment is not possible to upgrade to higher version of NetBackup because of old HW.

Backup ending with: ERR - Cannot write to STDOUT. Errno = 110: Connection timed out

I found one Technote where is discribed how to disable IPv6, its done, but backups still cant work and errors are the same.

<16> flush_archive(): ERR - Cannot write to STDOUT. Errno = 110: Connection timed out
<16> bpbkar Exit: ERR - bpbkar FATAL exit status = 24: socket write failed
<4> bpbkar Exit: INF - EXIT STATUS 24: socket write failed

Here are host_info settings:

# cat host_info
CONNECT_NON_RES_PORT 0
DYNAMIC_ADDRESS 0
FREE_BROWSE 0
LIST_RESTORE 0
MAX_JOBS_THIS_CLIENT 0
NO_CALLBACK 1
WOFB_ENABLED 0
WOFB_FIM 0
WOFB_USAGE 0
WOFB_ERROR 1
DAEMON_PORT_TYPE 3

 

See bpcd and bpbkar logs attached.

 

Thanks in advance.

    Have you tried to re-boot the client ?

    Seems the file system backup abort while accessing /bin and /etc.

    Yes client server has been rebooted, once after ipv6 has been disabled and a few times later was inetd and NIC rebooted.

    From log you can see issues with /bin and /etc because I specify only these folders to backup in file list specification, not whole / directory. Its still the same for each folder/subfolders.

     

    Here are some setings from client:

    # sysctl -a|grep tcp_timestamps 
    net.ipv4.tcp_timestamps = 1
     
    # cat /etc/sysctl.conf 
    # Disable response to broadcasts.
    # You don't want yourself becoming a Smurf amplifier.
    net.ipv4.icmp_echo_ignore_broadcasts = 1
    # enable route verification on all interfaces
    net.ipv4.conf.all.rp_filter = 1
    # enable ipV6 forwarding
    #net.ipv6.conf.all.forwarding = 1
     
    Do you think its right or something should be changed?

    Logs (bpbkar, bpbrm, bpcd, bptm) on media server are enabled. Log bpbrm not.  

    Bptm log from media server attached.

    Just had a look at bpcd log - all seems fine till right at the end:

    10:45:26.758 [31420] <16> bpcd main: read failed: Cannot assign requested address

    Previously this line followed successful server name comparison:

    10:06:10.321 [21492] <2> bpcd main: output socket port number = 1

    So, this looks like a problem at OS level where no more output sockets can be assigned.
    You need to speak to OS admins about this.. or look for ways to increase socket connections on a Linux forum...

    Hi,

    we changed some network settings on OS side, some timeouts etc. but nothing changed, still the same situation.

    There is no support for old Suse 8/9 server so we ask for reinstalltion to newer version, we still wait for approval.

    I'll ry reccomendations from your last post, perhaps it will help. Thanks.
