Re: [exim] Exim 4.88(9): failed to read pipe from transport

Hello.

Please help solve a problem with send mail to many users via smtp
transport with TLS (Exim 4.88 or 4.89 RC5).
Error:
failed to read pipe from transport process 19966 for transport smtp:
required size=2816 > remaining size=2811 and unfinished=false
or:
smtp transport process returned non-zero status 0x0100: exit code 1


remote_smtp:
driver = smtp
hosts_try_chunking =
tls_try_verify_hosts = :



It's from debug when seding frozen message (exim -d -M msg_id):
