Import throwing "java.lang.StackOverflowError"

Hi Gurus,

We are trying to Import some types to the Test server. While doing “ Preview “ the Logs says Import successful but when we “Submit” it, it ends up throwing "java.lang.StackOverflowError" in the MS logs.

We tried to increase the heap size for MS and SM. We have also logged with PTC Tech Support but there is no response to it till now.

We are using the Windchill 9.1_M050 .

Any pointers to this will be highly appreciated .

Thanks

Mayur.
