My apologies for the incomplete reply, it got sent out before all details went it.
To continue the initial thread: I'm trying to run a full ltp test run on Ubuntu 14.04.2 as a Hyper-V VM. The VM is set with 8 or 12GB and 4 vCPUs, however during the tests execution the syslog records over 30 call traces similar to the one below. Haven't tried vmware or other platforms, but I'm wondering why LTP processes go over the limit, or what would be a reference system resources that would accommodate a full run. Otherwise, are there are params that can limitor specify the resources that LTP can use?
