During execution of RWTCmd (RC Wintrans v. 10) from time to time application returns error code -1.

Important seems is that any calls of RWTCmd does not have /a or /keepalive arguement (it is strongly expected as RCWinTrans with this arguments does not deallocate memory)

Process we have implemented:
1. checks if database is up to date (argument /IsUpToDate)
2. If database need to be updated we call argument /Update
3. Finally we generate output file using /WriteTargetFile

Error code -1 is returned (not always) on any step of our process.
Problem does not occure if all calls are with /a or /keepalive

Can you please tell us what -1 error code means ?

This is possible. Not using /a then RC-WinTrans is closed and started again (as COM server) for the next command from RWTCmd.exe.
Closing RC-WinTrans takes time to free all COM objects and to free the .NET Garbage Collection (GC). It depends on the size of
a project how long it takes to free all. RWTCmd is fast to call the next command and to start RC-WinTrans again -- before all objects are released from the previous command (previous use of RC-WinTrans).

Try: Use "Wait"/"Sleep" before calling RWTCmd for the next command. For very large projects it can take up to 1-2 minutes
until the GC is cleared and all COM objects are released -- it depends. Try it with a "Wait" of 15 sec..

We solved this problem by repeating RWTCmd call in loop up to 100 times with delay 2 seconds if returned error code is < 0 but it does not look nice and I think in professional usage (where you hve to translate ony by one several components) case serious problems. Additionally there is no possibility using RWTCmd write all output files of all language in one shot... becasue of this number of calls to RWTcmd increase (there is possibility to use API which I'm going to check)

I think problem in general is change introduced since RCWinTran9 where it is no longer possible to to start parallel operations (2 calls from batch mode in the same time). It is not possible becasue automation server in which RCWinTrans is working is started in UI mode (1 instance). For us it is serious problem becasue builder normally manage many components in the same time... so for now time of build explode becasue we have "bottle neck" by RCWintrans (we have to have queue of builds waiting till RCWintrans complete previous operation build support).

Why idea working very nice on v7 was changed ?

This is true.
Only (1) one instance of RC-WinTrans is started/used. And: (2) RC-WinTrans is started (as COM server) as
normal application (UI mode).

(2) UI mode: We cannot change this. RC-WinTrans must be started and used as COM server (as UI application).
(1) One instance: We will strive to solve this for the next service release (February/March 2016).
