Nothing happens when starting action

Issue summary​

While working in MTA and trying to start any of below actions:

in some occasions, it may seem like nothing happens.

Possible causes and resolutions​

Too many asynchronous processes are running simultaneously​

When executing any of above mentioned actions, they are executed in the background by MTA. To prevent MTA from running out of memory because some processes use up a lot of resources, these actions can only be ran simultaneously 3 or 4 times. If someone tries to run another action of the same type, nothing seems to happen right away. This does not mean the action will not be started; MTA will wait until one of the running processes ends to start a new one. Given the nature of these actions however, this could take a couple minutes.

Resolution

In short; wait a little longer, or cancel the action and try again when fewer users are working in MTA. Or: contact other endusers working in MTA to see if their process can be cancelled, because (for example) a connected debugger has frozen a Test Run with a breakpoint.

If a process takes longer than an hour and does not seem to progress, contact support.
