I'm using homebrew on CentOS Linux. Anyone have seen this problem?

Answer 1

The issue is permissions on /tmp directory even though error does not say anything about it. QuestDB is Java and Java uses hardcoded /tmp as temp directory on Linux and does not try to use any environment variables to override it. QuestDB tries to load native binary and java uses `/tmp' to unpack and load it from.
The only solution is to add exec permissions to '/tmp' directory to the account which runs QuestDB.
