Re: [mosquitto-dev] Cross compiled mosquitto_pub gets stuck 

I regularly run the mosquitto clients on both MIPS 4KEc V6.4 and
MIPS 24Kc V7.4 and have no problems at all. (OpenWrt)

Is it possible your system has unusual signal numbers? There were
some quirks with uclibc a (very) long time ago that I had, iirc.

Cheers,
