Some of our backups are failing; with error “IPC Read Error System error: [104 & 10054]” connection reset by Peer DP 8.14; error code 104 happening on Linux client and 10054 on Windows machines. We are running Cell Manager 8.14 on Windows 2012. We have two instances of DP Cell Managers. Each Cell Manager has DP clients. The two Cell Managers are not connected.
After looking into the Windows Event logs, we noticed that these error occur at the same time as Group Policy refresh on the Cell Manager host. We noticed that one of the group policies wasn't propagating properly on the DP Cell Manager host. We fixed policy. The Group policy fix seemed to have fixed the issue on one of the instances of DP. However, on the second instance, we are still encountering the "connection reset" in DP. This is still happening at the same time as GP refresh (despite the GP propagating properly with no errors).
I read somewhere that activating the OB2IPCKEEPALIVE solves the issue. But this parameter appears not to be present in DP 8.14. Can you help with a permanent fix or how we can troubleshoot the issue as this as this has been happening for quite some time?
