When running more that one job inside a pod cannot submit more than one job reliably. If more that one job is summitted in succession we get a input output error. This problem can be mitigated by xbutil reset from the host before a pod is spun up but this is not a desirable .

Any feedback would be grateful.

Hi @iavssw, this issue may related to the XRT container solution, could try to run this test under a pure container environment without k8s and see what happens? If it can be reproduced, I suggest to reach the XRT team for further help.
