Tcmalloc issues

calendar_today August 26, 2026 person @amizne_yugabytedb Amiram Mizne domain yugabyte

Hi @marknefedov - Thank you for the detailed report. The crashes come from tcmalloc’s per-CPU cache, depending on rseq behavior that kernel 6.19 changed. Upstream treated the change as a kernel regression and reverted it, so the fix is on the kernel side.
