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?

NAME

       bssh/bvnc/bshell - Browse for SSH/VNC servers on the local network

SYNOPSIS

       bssh

       bvnc

       bshell

DESCRIPTION

       bssh/bvnc/bshell  browses  for  SSH/VNC	servers  on  the  local  network, shows them in a GUI for the user to select one and finally calls
       ssh/vncviewer after a selection was made.

       If the binary is called as bssh only ssh servers will be shown. If the binary is called as bvnc only VNC servers  will  be  shown.  If  the
       binary is called as bshell both VNC and SSH servers are shown.

OPTIONS

       -s | --ssh
	      Browse for SSH servers (and only SSH servers) regardless under which name the binary is called.

       -v | --vnc
	      Browse for VNC servers (and only VNC servers) regardless under which name the binary is called.

       -S | --shell
	      Browse for both VNC and SSH servers regardless under which name the binary is called.

       -d | --domain= DOMAIN
	      Browse in the specified domain. If omitted bssh/bvnc/bshell will browse in the default browsing domain (usually .local)

       -h | --help
	      Show help.
