Petsc Error

[Berend van Wachem]

Hi,

I ran the same command again, running top, and got the result

Mem:   6220940k total,  5879056k used,   341884k free,   143992k buffers
Swap:  1951888k total,     2584k used,  1949304k free,  2363516k cached

   PID USER      PR  NI  VIRT  RES  SHR S %CPU %MEM    TIME+  COMMAND
19117 berend    25   0 3037m 2.5g 3508 R  100 41.4   0:44.96 MultiFlow



just before it crashed. I have a 2 processor machine with total 6 GB of 
memory (2 times 3 gb?), so I don't think it should be out of memory. How 
can I verify this for sure?

Thanks,

Berend.
