I have a host with AIX 6.1 (6100-04-02-1007) upgraded from AIX 5.1 with Veritas Storage Foundation 5.1.
Since the upgrade from AIX 5.3 to 6.1, Run vx services means a lots of memory consumed that I can not explain. This memory appears in 'nmon' as System (see below System 41.2%). If I do not start Veritas it is <20%.
Whay does mean that "System" memory? How can I know what is consuming this memory?
