RTC-CC Synchronizer fails through cleartool error

Hi there,

again it's me with a synchronizer problem.
I do often have the problem that the synchronizer fails through those cleartool errors:



This message describes that the clearcase process could not be contacted ... but why?
When I just rerun the synchronization process than everything works.

The clearcase log just gives me this:


I think WINSOCK errors can mean everything or nothing ...

But this is really annoying as if the synchronizer shall be running automatically and you get often such an error you have to run it manually ... :(

Any ideas?

Greetings,
Simon
