@stlammel : thanks for reporting this issue, unfortunately I cannot reproduce it either in my environment. Could it be that you are running out of memory on the ETF node? The sego happens at `/usr/src/debug/xrootd/xrootd/src/XrdSut/XrdSutBucket.cc:85` which is a memory allocation: https://github.com/xrootd/xrootd/blob/cf4c57b51ef4d7ba3756583d8c3af628326f3ffd/src/XrdSut/XrdSutBucket.cc#L85 What is the platform you are running on your test, is it Centos7 (RHEL7)? What is the exact version of xrootd client / server you are running? I could provide xrootd RPMs built with ASAN, could you use those in your tests? This would give us invaluable insight in case of another crash! -- Reply to this email directly or view it on GitHub: https://github.com/xrootd/xrootd/issues/1870#issuecomment-1397114951 You are receiving this because you are subscribed to this thread.
