Asset import is blocking all available Caesium threads

[Stefan Stadler]

Hi all,

I have observed some strange behaviour in our environment.

When an import of Asset objects is happening (this happens quite regulary), there are no incoming emails processed. I managed to get a thread dump while the issue happened and found the following listed for all Caesium threads, that appear to be responsible for email processing:

As all the threads appear to be blocked by Asset importing new objects, I am wondering, how I could prevent that.

Currently we are running 10 workers for importing. The import still takes about 40min to complete in some cases. Could this be too much and reducing it might help here? Or are there any other tweaks for that?

Thanks for your help!

Stefan
