does anybody else have some suggestion to solve or identify the reason causing the Digi Portservers to freeze?
running out of ideas here and we’re considering to replace Digi devices with Perle…
- Ensure the latest firmware is applied.
- If using port sharing:
- Check for flow control buffer overflows by issuing “display ports” from the command line of the unit:
- If running RealPort, please advise what operating system/version.
1.Latest Digi driver is installed.
We tried already to exchange the Digi unit with a new one, but this did not helped.

- Port sharing is used and we are actively reading the data from both hosts.

- In normal operation, there is no indication for flow control buffer overflows (OFC or IFC)
Unfortunately there is no possibility to connect to the Digi Unit when this “freezing” situation occurs, as TCP/IP access is not possible anymore.

- We are using Solaris 10 hosts and latest Realport driver version 2.8.5
The problem was noticed for hosts with SPARC and X86 architecture.
Do you have any other suggestion?
Thank you!
Port sharing is not supported with any Unix variants running RealPort. You should use TCP socket communication if port sharing is necessary.
where did you get this info that Port sharing is not supported for Digi PortServer TS series with Realport on Solaris 10?
I know that it is not supported for the new Digi ConnectPort LTS models, (and Raw TCP socket should be used instead for these models)
But for the old Digi PortServer TS8/16 or Digi One, sharing mode should be supported for Solaris 10 and RealPort.
There is also this Redundancy white paper available from Digi:
http://www.digi.com/pdf/wp_redundancy.pdf
Port Sharing works when using TCP sockets and the Windows RealPort drivers, however not when used with Solaris/Unix/Linux RealPort drivers.
