Solaris 10 Shared Memory Corruption with X11
I am having a problem with shared memory corruption. I have two 86 servers running Solaris 10 (150400-06). One of the servers is accessed by a Sun Ray thin client Version 11.1.3.0.2.6. I login into server one from the thin client. I then ssh -X to server two. When a process that contains a Java GUI is started on server 2 sometimes it will override another process’s shared memory on server 1. I found a simple scenario which causes the issue. I reboot both servers, login into server one from the Sun Ray, then ssh -X from server 1 to server 2 and run JConsole. The first time JConsole is started the images on the top of the GUI is corrupted. The second time JConsole is started the images on the top of the GUI are partially corrupted. The third time JConsole is started the display is correct. When I start my process that accesses shared memory and I start JConsole and the images are corrupted my process's shared memory becomes corrupted. I have tried JRE 1.6.20 and 1.6.65, and both Xnewt and Xsun. I have set the shared memory environment variables to both true and false in the dtprofile on both servers (always the same on both servers). It seems that the GUI images are over writing memory on server 1. Has anyone seen this behavior?

install-solaris(1M) install-solaris(1M)
NAME
install-solaris - install the Solaris operating system
SYNOPSIS
install-solaris
install-solaris invokes the Solaris Install program. Depending on graphical capability and available memory at the time of invocation,
install-solaris invokes either a text-based installer or a graphical installer.
The following minimum requirements for physical memory dictate which features are available during installation:
For SPARC machines:
128 MB
Minimum physical memory for all installation types
128 MB
Minimum physical memory required for windowing system
384 MB
Minimum physical memory required for graphical-based installation
For x86 machines:
256 MB
Minimum physical memory for all installation types
256 MB
Minimum physical memory required for windowing system
512 MB
Minimum physical memory required for graphical-based installation
In some cases, even if the minimum physical memory is present, available virtual memory after system startup can limit the number of fea-
tures available.
install-solaris exists only on the Solaris installation media (CD or DVD) and should be invoked only from there. Refer to the for more
details.
install-solaris allows installation of the operating system onto any standalone system. install-solaris loads the software available on the
installation media. Refer to the for disk space requirements.
Refer to the for more information on the various menus and selections.
