pespin gerrit-no-reply at lists.osmocom.orgpespin has submitted this change. ( https://gerrit.osmocom.org/c/osmo-gsm-tester/+/22598 ) Change subject: srsue.conf.tmpl: reduce nof PHY threads to 2 for ZMQ ...................................................................... srsue.conf.tmpl: reduce nof PHY threads to 2 for ZMQ we've detected a possible race condition during the Msg3 transmission that caused the thread that sets the Msg3 grant to be delayed. The PHY worker that executed TTI+2 finished by that time already and didn't even see the pending UL grant. This is issue is more likely to happen on loaded system, for example when running parallel ZMQ jobs. We therefore decided to reduce the number of parallel PHY workers to 2 so the issue is circumvented.
