TDP for VE 6.3 - ANS9365E VMware vStorage API error, API RC 60, TSM RC 115

[misic]

We are experiencing frequent "Operation timed out" and "Cannot create a quiesced snapshot because the create snapshot operation exceeded the time limit for holding off I/O in the frozen virtual machine" error messages on different VMs and different data mover nodes.
TSM server OS: Windows 2008R2. Any suggestions for the corrective action is highly appreciated.

Storage Management Server for Windows: Version 6.3.1
TDP for VE: Version 6.3
VMware vCenter Server: Version 5.0.0
vSphere Client: Version 5.0.0
