    Could be a number of causes - the extra ports used by NetBackup often causes the issue - as you are on Windows 2008 try the following (the registry one needs a reboot - the netsh takes effect immediately), these will increase the number of ports available and reduce the time wait delay to free ports up quicker:

    HKLM\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\
    Add a new DWORD – TcpTimedWaitDelay  - Decimal Value of 30
    netsh int ipv4 set dynamicport tcp start=10000 num=50000

    Next - to keep communications with the Storage Server running better add the following flat file to the Master and Storage Servers:

    <install path>\veritas\netbackup\db\config\DPS_PROXYDEFAULTRECVTMO

    open it up in notepad and put a value of 800 in it

    All of the above can really help with this issue

    Hope this helps

Thanks Mark,

i have some questions before applying it.

Netbackup support already asked me to put thos 2 files onm y media servers and put 1800 in it.

<install path>\veritas\netbackup\db\config\DPS_PROXYDEFAULTRECVTMO

<install path>\veritas\netbackup\db\config\DPS_PROXYDEFAULTSENDTMO

It improves the situation but I still got the error after a week. Maybe it's happenning when i have more stuff running on the week-end. SHould i really put it at 800? If yes, can you explain?

 

Next, for the Netsh command,  here is my actual config if i enter "netsh int ipv4 show dynamic tcp"

Protocol tcp Dynamic Port Range
---------------------------------
Start Port      : 49152
Number of Ports : 16384

Should I still enter what you told me ? "netsh int ipv4 set dynamicport tcp start=10000 num=50000"

FOr the registry key, i have nothing for the moment so I will try.
