After monitoring the execution of the process we notice that it
continues to allocate phy memory but virtual memory doesn't seem to move
at all. We are using deferred mode for allocation. Here is the output of
vmstat and swapon -s
Swap partition /dev/rz8b:
Allocated space: 135934 pages (1061MB)
In-use space: 5765 pages ( 4%)
Free space: 130169 pages ( 95%)
Total swap allocation:
Allocated space: 135934 pages (1061MB)
In-use space: 5765 pages ( 4%)
Available space: 130169 pages ( 95%)

Subject: Process reaching some limit
Tru64 4.0D
Managers, I am troubleshooting a problem with a process that is crashing
during execution with a Malloc error. The developers are telling me that
it seems to be when going above 900Mb. Everything that I see says that
memory allocation per process is 10Gb. I have included the current proc,
vm, and ulimit settings. Please help. Thanks
