[cisco-voip] UCCX 9.0(2) SU1 DRF JSCH exception

[Erick Bergquist]

Hi,

Maybe one of the Cisco folk will chime in..

I'm seeing an occassional backup failure every few weeks on UCCX
9.0(2) SU1 where there is a JSCH exception and UCCX can't connect to
the SFTP server.

There was a bug in CUCM and we upgraded CUCM which resolved this
issue, but I am not seeing this bug listed on UCCX side. 9.0(2) SU2
release notes nor bug search tool come up with anything on this.

The CUCM bug id is CSCul44464

Here is DRF trace log from UCCX,
