The stack trace simply shows everyone waiting for things to complete. It does not tell me what is waiting for what nor how many different clients are in this state. I must admit that release 4.12.4 is very old (2020-09-03). Any chance you can upgrade to a supported release? Otherwise, the only thing left is with running the sever with additional tracing enabled and after that a core file. Frankly, something weird is going on with that machine. When did this start happening? What changed roughly at the time this started happening? -- Reply to this email directly or view it on GitHub: https://github.com/xrootd/xrootd/issues/1799#issuecomment-1311611025 You are receiving this because you commented.
