Task name

PowerShell

Task version

2.247.1

Issue Description

On our self-hosted machine/agents, there are times when just initialising the PowerShell tasks takes more than a few seconds. Most recently, it took half an hour, so the overall pipeline failed as it exceeded the maximum time. it isn't consistently the same task in the pipeline, but it is only ever a PowerShell task.

This only occurs on interactive agents used for UI tests, agents run as a service use the same scripts but don't suffer the same issue.

@dlaw1912 Verified the error log which you have shared and found it got stuck before it started the task execution. It's an issue with agent which you have used for it as it got stuck after verifying the space on the agent.

It's not a task issue and issue from agent. Please check what happened during that duration. Please also let us know did you faced the issue again or it has happened only once. As you were using self hosted agent, please verify from your end on the agent.
