ADE L: could not open logFiles during a parametric sweep on a transient simulation

Hi cadence ADE L suers,

My cadence is installed on Redhat linux and I am running Virtuoso 615.

When I do a parametric test (sweep temperature) on a transient simulation, the simulation stopped after the first temperature point successfully run. I got a message in CIW window saying

    *Error* Could not open logFile: /home/users/proj1/design1/simulation/test1/spectre/schematic/psf/artistLogFile

    I checked that file and it is empty. When I closed that file it says E72: Close error on swap file.

    Does it mean I don’t have enough swap space? Seems like the simulator is filling up the partition when this happens.

     But cat /proc/swap shows the following:

     Filename       Type          Size          Used     Priority

     /dev/sda3     partition      2096472  615944      -1

According to this I should have enough space, right? What does -1 priority mean?

Thanks for your help.
