the only thing causing this is a failure to create a thread
https://github.com/MariaDB/server/blame/10.5/mysys/thr_timer.c#L94

and the only recent change would be https://github.com/MariaDB/server/commit/ad17c98dd5877ededb8ac3d4e0ac1f7beed5406c, MDEV-16264, a 10.5 thread stack size increase from 8k to 64k.

Tuned most server vars, many to maximums. Will see if this happens again. Thanks for the input from various people here & elsewhere.
