Issue

When you start Adobe Flash Media Server (FMS), you encounter a failure that returns the following error message in the logs:

Failed to create process condition: errno(28)

This issue also occurs when FMS attempts to launch more cores to handle more applications, instances, or clients.

If the system is running out of semaphores, raise the maximum number of arrays.

Approximately four times the number of cores + 10 fixes this issue.

Note: If the system is using semaphores for another program, such as a database, add 1024 to the baseline number.

To change the maximum number of arrays, first get the old values, then change the last number to 1024 and set the new values, as follows:

Execute the following command:

$ sysctl kernel.sem (This command prints a value to the screen as follows):

kernel.sem = 250 32000 32 128
Next enter the following:

$ sysctl -w kernel.sem="250 32000 32 1024"
Restart Flash Media Server. Use "ipcs -su" to see how many semaphore arrays are created, as described in the Additional information section.
If the above commands worked properly, execute the following command below to make the change permanent:

$ echo "kernel.sem = 250 32000 32 1024" >> /etc/sysctl.conf
Execute the following to verify the above command and make the change active immediately:

$ sysctl -p Note: Run the command as root or sudoed, and if /sbin isn't on the path, run the command as /sbin/sysctl.
