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?

lsmsad

lsmsad(8)						      System Manager's Manual							 lsmsad(8)

NAME

       lsmsad - Starts the Storage Administrator (SA) daemon

SYNOPSIS

       /usr/sbin/lsmsad

DESCRIPTION

       The SA daemon, lsmsad, is a process required by lsmsa, the SA graphical user interface (GUI). The daemon issues commands and obtains system
       information on behalf of SA.

       The SA daemon runs on a Tru64 UNIX system on which LSM is initialized and running.  The SA client runs on any  machine  that  supports  the
       Java Runtime Environment.

       The SA daemon is automatically started at boot time. Under normal conditions, the daemon does not need to be run manually.

       If SA does not start during the boot process, enter:

       /sbin/init.d/lsmsa stop

       To restart SA, enter:

       /sbin/init.d/lsmsa start

       Only one SA daemon can be running on a system at a given time. If a second SA daemon attempts to start, it will fail.

RESTRICTIONS

       You must be root user to run lsmsad.

FILES

       The script that starts lsmsad at boot time.  The command log file that tracks SA tasks.	The access log file that tracks login to  SA.  The
       server log file that tracks server startup information and server errors.  The log maintenance shell script that saves and  compresses  log
       files.

SEE ALSO

       lsmsa(8), volintro(8)
