Hi, can you provide more details like exact parameters which you are using so I can replicate the issue?

Could not get memory 'psm_b3b595e8 could mean the shared memory block has been deleted/cleaned-up too early but it's hard to know what's causing this without further details.

My first guess would be, that the shared memory got stale, because you were not using a context manager. Happened to me.

You should always protect an UltraDict from multiple writes at the very same time like:

udict=UltraDict()
with udict:
    udict[some key] = some str

...my 2 cents on the matter.
