KRE hangs on Linux

We have been running KRE for a while 100s of unit tests in a Suite, and everything is working well until we decided to create a dedicated server to run KRE, that’s when things started to break.
The tests run faster on the dedicated ubuntu environment (roughly 20% faster), but then it just hangs after executing 50 tests, and then it starts to crawl (roughly 2 minutes delay in each test)
See this log

The issue is not CPU or RAM limited, we tried different scales doubling each, we also tried different cloud providers, and it was all the same. When we tried a Windows server, the problem wasn’t there (although it was slower than Ubuntu in executing the first 50 tests), so the problem appears to be related to the Linux version of KRE (Katalon Version: 8.0.5)

Any help in how we can resolve this issue is appreciated.
