Is there a known limitation on the number of spring connectors?
In my problem I get the answer "Internal Error" during the task "Establishing Spring Connector" and then the linear analysis is stopped.
If I suppress a part of the connectors (I have 950 of them) the problem disappears
It was not a problem of quantity of connectors. After many hours of tests I found the unique connector which caused the internal error. I have not found any particularity of that connector which could justify its behavior different from the rest of connectors.
