> cpu utilization 100% and i do not get any response.
> We have 2 bad approach:
> 1. In org.teiid.olingo.web.OpenApiHandler:151 teiid create tmp file in filesystem.
> Its bad because in Docker k8s systems applications can't create any files in FS.
> 2. In org.apache.xalan.transformer.TransformerImpl:709 we get system freeze (CPU utilization 100% infinite)
