Interrupt SIGPIPE messages

[Malcolm]

Hi,

I keep getting messages in my fhem log like this

Interrupt SIGPIPE at /usr/local/lib/arm-linux-gnueabihf/perl/5.28.1/HiPi.pm line 79.

I'm running fhem on a raspberry pi and using HiPi for SPI comms in a module I'm coding.  I don't

always get these messages and I can't find a reliable way to repeat them but they do seem to occur

fairly often each day.

How do I fix or stop this?

Thanks
