What's your stack size limit?

Depending on your distribution there may be system-wide limits,
limits in initscripts for particular services, like

  [root at server ~]# ulimit -s
  8192

or systemd, which ignores the latter:

  [root at server ~]# systemctl show redis | egrep "^Limit"
  [root at server ~]# systemctl show rspamd | egrep "^Limit"

  LimitCPU=18446744073709551615
  LimitFSIZE=18446744073709551615
  LimitDATA=18446744073709551615
  LimitSTACK=18446744073709551615
  ^^^^^^^^^^^
  LimitCORE=18446744073709551615
  LimitRSS=18446744073709551615
