Subject: Re: [daos] Timeouts/DAOS rendered useless when running IOR with SX/default object class

A final "Hi" on that topic,

we have discovered the reason for the issue: The ulimit on the _server_

side was too low and it differs between regular users and daemons like

the DAOS server. For the latter it was set to soft 1024/hard 4096. We

increased it to 50000 respectively by modifying the service/unit file.

With that we did multiple IOR runs with up to 48 processes and SX object

class from a single client node without any errors.

We noted that the coredump end memlock limits are already "increased" in

the server's unit file. Maybe it is a good idea to increase the file

limit as well by default, although the limit may depend on the provider

in use.

Regards, Steffen
