Unexpected Error: "Element already read to the end"

Hi
I'm using the .NET/COM object in a big automation project. Things worked very well until I installed a new WinCSP version (5.7.6 (Build 5874)). Since then I'm getting error "Element already read to the end" all the time ! When my tool starts, it opens WinSCP connections to various servers using corresponding WinSCP Object instances. Interesting is, this problem does not arise at the beginning of my tool's usage, but at a random time (which can be even hours !) later; but as soon as the problem pops up nothing goes anymore and no recovery possible other than restarting the tool itself.

I would be very gratfull to get your immediate support on this, because it is preventing us from running highly important Test-Automation processes

Thanks in advance for your support

Please attach a full debug log file showing the problem.

I too am experiencing this exact same behavior. I will provide a log file if OP does not.

I've been analyzing the problem for days, trying to correlate the error happenings with the Session Log infos. It seems to be, that under certain circumstances, for example when running remote commands that take longer times to execute in UNIX, a timeout (session timeout ??) triggers and the session is broken (bye bye :-( ), so all subsequent session operations throw the error "element already read to the end". As soon as my analysis is definitive I will send the LOG infos to the OP

Attached is a summary Session Log File. Problematic areas are those containing text like:
1) Host is not communicating for more than 15 seconds
2) If the problem repeats, try turning off 'Optimize connection buffer size'
3) Scheduling output: [(A)bort (60 s): Abort]
4) Exception: WinSCP.SessionLocalException: Session has unexpectedly closed

These problems seem to be correlated to commands like:
Command: [call /home/mtx/Automation_Framework/listFiles.pl '/mnt/shared/exchange/preBx/*.tlc' 'BSC:SUB:2051619' 10000 '(split(/-/,$a))[4] <=> (split(/-/,$b))[4]']
Which very often take even several minutes to complete
