The issue is seen in 2 ways:
a) The task in the graphic below does not complete:

b) The following error is seen in the /var/opt/VRTSsfmh/logs/error.log file:
gzip: /var/opt/VRTSsfmh/zHkGP_7CMv/vom-8.0.0.510.tar.gz: not in gzip format
Out of memory!
The VIOM management server is not configured with enough memory. The issue can also be seen if the /var or /tmp do not have enough free space.
Increasing memory used by the VIOM Management Server to a minimum 4GB and ensuring that both /tmp and /var are not full, should allow the operation to be completed.
Upload of patch 8.0.0.510 within Veritas Operations Manager (VIOM) console hangs.
