How many CPUs does your server have?

Two physical cores, four if you count x86 hyperthread "processors."

This is a particularly high thread setting. Most often, a lower setting results in better performance (I generally use 8 threads on dual-CPU systems). Having too many threads has resulted in strange behavior for me in the past as well.

FWIW, slapd has been rock-solid on this hardware with this (or essentially similar) configuration since before 2.1.30 up through 2.3.30. We skipped forward to 2.3.41, and started seeing these crashes. However, we weren't using syncrepl until 2.3.41, either.
