SSHv2 example with errors

Hello,
I am developing (with a DIGI Digi Connect ME Digi JumpStart Kit for NET+OS 7 w/Eclipse in a DC-ME-01T-C)a SSH application. I compile the sshv2 example and all is ok, but when i upload a file the file is transmitted but dissapears from the directory so i can not connect to ssh server. I also compile the project with the in-code keys and i obtain this console messages:
IAM:Got AUTO-CONFIGURED IPv6 address FE80::240:9DFF:FE43:3597 on interface eth0:3
IAM:Got STATIC IPv4 address 192.168.0.108 on interface eth0
Network IP configured.
CLI Started.
FTP server is ready.
SSHv2 server is ready to accept incoming connections.
Waiting for new SSHv2 client to connect…
panic: Unable to Create ThreadX Semaphore, in file tfKernelCreateCountSem, line number 0

My problem is that i can not understand why appears the last message:“panic: Unable to Create ThreadX Semaphore, in file tfKernelCreateCountSem, line number 0”
Anyone has any idea?
Thank you

Re-installing the Net+os in other folder solves the situation, and now work every example.
Thank you
