For some products the 'Get Latest Maintenance' or 'Update Product Release' task will hang at about 50% completion and then stop until the MSMTC is recycled and cancels the task.
1. Update the CA CSM PASADVOP member with the following values:
firewall.friendly=false
default.timeout=120000
control.keep.alive.timeout=50
For CSM 5.1 the PASADVOP member can be found at CA CSM *.CUSMAC(PASADVOP)
For CSM 6.x the PASADVOP member can be found at CA CSM *.SAMPLIB(PASADVOP)
2. Recycle the MSMTC and then try the 'Get Latest Maintenance' or 'Update Product Release' task again.
