Central instance fail non startup due to SNC error

Hi all,

we are using SNC for all our system, and now we are going to change the hardware on our landscape.

As preparation activity we had recreated test system with a systemcopy.

All went well except for the fact that when we start the central istance the workprocesses die with the error below unless we reboot the server before start the instance:

S  size of spec char cache entry: 297032 bytes (timeout 100 sec)

S  size of open spool request entry: 2512 bytes

(SID and COMPANY are just used to cover real name due to privacy rules of my company)

Is it possible that we need to install a window fix?

Thanks for your time and regards

    Hi Federico,

    Please create credentials (= assign password) for your SNC PSE, as it
    is described in the online documentation:

    Thank You.

             Do you have to generate some certificate through  tx STRUTS? Where Do you download the last version of the .dll library?
