apparently, all file descriptors have been consumed. I increased the limit to
16384, and then the crash would look similar, with the last line reading

close(16384)                             = -1 EBADF (Bad file descriptor)

May be related, the trace is full of messages like

recvmsg(3, 0x7ffffd5c88b0, MSG_CMSG_CLOEXEC) = -1 EAGAIN (Resource temporarily
unavailable)

maybe that's the reason it's running out of descriptors?

Of course, it's very annoying not being able to start my main mailer :-(
