OMSA 11 failed to start at Dell R750

Hi there,

We rent huge amount of Dell servers from our hosting provider, but they told they don't provide support for software, only for hardware. Therefore I'm reaching you for the help.

We are running server Dell PowerEdge R750 with Oracle Linux 8.8 on top, with OMSA 11.0 installed.

It was installed from original Dell yum repository. All firmware are up to date. Kernel (red hat kernel) is little bit not up to date (other servers with same kernel don't have this issue though).

We have encountered a problem on some servers, that OMSA failed and could not be started/restarted.

At logs we see that some OMSA processes failed to start:

I killed all omsa processes and cleared semaphores and tried to restart it again.

But nothing helps.
