Can you check the network settings on the HMCH1143 server. If this is
running half duplex, or particularly slow then the sessions will lock
parts of the target disk storage pool and hold them. This may be
directly conflicting with the migration process. As previously stated,
this could also be a potential problem with the disk performance on the
target pool.

on...
Suggestion
Assuming that data(s) are being migrated from diskpool, I would also
examine if disks of primary diskpool are going bad or there are some bad
data written to disk.
I would look at /var log or error logs. Maybe run some diagnostics
commands top see if OS see all devices are fine on the TMS server.
