Describe the bug

I am running amemgym benchmark using memmachine semantic memory:

https://github.com/AGI-Eval-Official/amemgym

While running eval, observe large number of semantic memory exceptions:

tomw@mac-work Desktop % grep '^Traceback' memmachine.stderr.txt|wc -l
903

it says task crashed:

 2026-02-26 18:34:51,156 [ERROR] memmachine.semantic_memory.semantic_memory - background task crashed, restarting

I suspect half of the add_memory operations are not completed due to the large amount of crashes.

Steps to reproduce

Info on running the benchmark is here:

Add memory succeeds
