Issues with idl_opserver crashing as a normal user on Linux [message #62093]

Hi,

I'm looking for a little guidance with regards to getting IDL 7.0
Workbench running smoothly on a 32bit Linux system.

The issue is that as a normal user, the idl_opserver process that
gets started by the Workbench dies right away.

This results in commands entered at the command line simply disappearing
and never getting executed. Also, I am unable to save new files or
create new projects and on exiting the Workbench, java hangs and
my CPU usage goes to 100%. I have to kill the java process manually.

Has anyone else come across this issue and does someone know of a fix or
workaround?

Thanks,

Christopher

A little more investigation on my part and I've solved to issue.

The shared memory needed for the Workbench and idl_opserver to communicate
was not available to normal users since the system didn't have /dev/shm
setup in /etc/fstab.

Here is the line I needed to add to /etc/fstab in order to setup shared
memory.

tmpfs /dev/shm tmpfs defaults 0 0

I hope this can help anyone else who comes across the issue.

Cheers,

Christopher
