Once I got a clean LVS, I ran RCX but I got an error.

#==========================================================#

*WARNING* Bad return status from RCX run. 0x2
#===================================================

I check the memory while I was runnung RCX. The total memory was 8GB.
RCX used 3.3GB and 5GB was free. Besides I had 20 GB of swap space. Is
this a memory problem or something else?

The second questions is the capgen. RCX automatically runs capgen or I
have to run capgen before running RCX? In the log file, I saw this.

Does this mean capgen was run?

Thanks in advance.
 
Sounds like it's trying to allocate > 2GB of memory at once on a 32-bit
system/binary and it's exceeding max int and wrapping around to negative.
Are you using a 32-bit or 64-bit machine? If it's a 64-bit machine then
you probably need to run a 64-bit Assura RCX/pax16 binary as well (if
there is one available). The fact that you have 8GB of RAM doesn't mean a
single process can allocate that much memory at one time. 32-bit systems
can only address 2-4GB of memory in a given process. I've never used RCX
but I've seen similar problems in other tools where someone tries to run
too large of a job for a 32-bit system/binary.
