With the debug option selected, additional files are added to the collection. This can cause the collection to reach the maximum size of 30 MB. When the collection is pulled remotely and at the max size, it can cause the system-httpd.slice to exceed the max memory. As a result the system recycles the processes in the cgroup to get back under the memory limit and results in collection failure. 

Future iDRAC9 Firmware 7.20.10.50 will automatically cleanup old corefiles to reduce debug collection size.

Use one of the following options to export the debug SupportAssist collection. 

Option 1
The core files can be deleted before pulling a remote collection to reduce the collection size. 

$ racadm -r %idracip% -u %user% -p %password% coredump 
$ racadm -r %idracip% -u %user% -p %password% coredumpdelete -f %filename%
$ racadm -r %idracip% -u %user% -p %password% coredumpdelete --all

Option 2
The debug SupportAssist collection can be pulled locally from the host system using local racadm. Using this method is not impacted as it does not run under the same cgroup memory limits as remote racadm. 

$ racadm supportassist collect -t debug -f TSR.zip
