Hi,

I am running some simple resource tests. For example, I start 20 nodes and monitor memory usage. Right after startup, it uses about 35Mb. It then gradually increases until it reaches its max at 64Mb after about 40 minutes, where it seems to stop increasing.

It doesn't matter whether I publish messages or not during this period. I have tried to tune zsys pipe limits, max message size, beaconing interval, evasive/expiration timeout, but still the same.

I am on a memory-constrained device and would like to keep the consumption as low as possible.

Anyone know why this is, and if it can be tuned?

I can see the same using the perf_remote test included in the Zyre lib:

zyre/src/perf_remote

Monitor the memory, and get:

Best regards,
