JVM crashes for multiple sikuli script on same machine

[Ritesh Ranjan]

Hi,

I have a sikuli script (written in Java converted to Jar). I am able to run the script on a standalone machine (single instance).
Logged in as another user, I copied the jar to other user home directory and tried to run the same script. It runs fine.

Now with 2 different sessions (putty session on different machines), I tried to run the same script on both sessions simultaneously. When I run the script on the second session, the JVM crashes on the first session, and vice-versa.

The crash displayed is as follows:
#
# A fatal error has been detected by the Java Runtime Environment:
#
# SIGSEGV (0xb) at pc=0x0000000000068686, pid=5961, tid=140614371464960

The crash dump (attached) shows error:

JVM is also crashing with me when I try to open more than one Sikuli-IDE on the same machine with the same user, but in a different VNC session.

I'm running Sikuli X-1.0rc2 x86_64, on a Red Hat Enterprise Linux Server release 6.1 (Santiago) through a VNC session.

cannot find the other bug on that matter, but as far as I remember, the solution is, to run different scripts under different users. The problem seems to be the home directory.

Sorry, but I mixed things up: bug 754020.
