According to man page, the only way it can return EINVAL (22) is either bad filter, or bad timeout. I can't see how the filter would be bad, so I'm guessing ts must be bad. Unfortunately I forgot to ask for it, so I am going to have to ask you run it again and run
p ts
if that's valid, then the only thing that can be bad if the file descriptor 23.

Hi,
can you run doveadm in gdb, wait for it to crash, and then go to frame 6 ( io_loop_handler_run_internal) and run
p errno p ret p *ioloop p *ctx p *events
Sorry but the crash doesn't make enough sense yet to me, we need to determine what the invalid parameter is.
