Hi -- I run 5.10.30 on an AMD 64 X2 dual-core processor. Normally, two tasks are running -- on one each core. Sometimes, one task stalls. Looking in the error log, I see many lines of this:

SIGPIPE: write on a pipe with no reader

What's going on here? How can I avoid this error and keep both cores working?

Not a clue. According to the signals list, it's signal 13:
Whenever a process tries to write on a pipe with no readers, it is sent this Signal. SIGALRM SIGALRM is sent when an alarm timer expires (counts down to zero). An application can start an alarm timer with the alarm(2) system call.

I'll ask a developer.

SIGPIPE != SIGALRM.
