Description:
============
Running TIBCO ActiveMatrix BPM using 64-bit JVMs on a Solaris platform, you may experience failures of the node process JVM, indicating a segmentation fault during startup.

Environment:
==========
TIBCO ActiveMatrix® BPM 1.1.1
64-bit Java Virtual Machines (JVMs)
Solaris 10 64-bit

Symptoms:
=========
The JVM running on the BPMNode crashes. Errors indicate segmentation fault.

Cause:
=====
The default values for Java extended properties in the BPMNode.tra file allow an insufficient thread stack for this environment.

Resolution:
=========
1). Log in to the TIBCO ActiveMatrix Administrator using either the graphical
   user interface or the command line interface.

2). Modify the JVM arguments for the affected node from Infrastructure > Nodes
   > BPMNode > Configuration > JVM arguments. (If it is not the BPM Node that
   is affected, substitute the name of the node you wish to change).

3). Add the following Java extended property:

    XX:StackShadowPages=20

4). Amend the following properties:

    XmX2g (from the default XMX1000m)
    XX:PermSize=192m (from the default 128m)
    Xss512k (from the default 256k)

5). Click Save.

6). To push the change to the actual node, click the Install button for that node.

7). For the new JVM settings to take effect you must restart the node. Stop the
   node and then restart it either from the ActiveMatrix Administrator or by using
   the TibcoHost stop and restart commands on the node's machine.
