I'm having trouble with increasing the allowed table elements per table in the pooling allocator - i'm hitting the hard limit of 20k


Test Case

Too big of a wasm file to upload here.... (32Mb), it is accessible here: https://github.com/MA3CIN/wasmtime-error/blob/main/wasm-server.wasm

Steps to Reproduce

Run the wasm file with wastime server: "wasmtime serve wasm-server.wasm"

Expected Results

I expected the allowed table elements per table in the pooling allocator limit to be increased when using the -W max-table-elements cli arguments

Actual Results

I'm still hitting the limit


Versions and Environment

Wasmtime version or commit: wasmtime 31.0.0 (7a9be587f 2025-03-20)

Operating system: Ubuntu 22.04.3 LTS

Architecture: N/A, single wasm instance

Extra Info

Works fine when i run it with wasmtime run, i only hit the limit with wasmtime serve..

Maybe a similar problem to https://github.com/bytecodealliance/wasmtime/issues/8504

Thanks! This is a bad interaction between the deafults of wasmtime serve which is to use the pooling allocator and the error messages here. You can fix this locally by setting -O pooling-table-elements=N. Additionally https://github.com/bytecodealliance/wasmtime/pull/10483 should fix this issue too.
