[exim] Re: failure to transfer data from subprocess
Is anybody able to assist with the below issue? The one thing I can say is that it doesn’t impact all email but it’s not clear what the criteria is of what it does impact. > On May 9, 2023, at 11:20 PM, Robert Nicholson > wrote: > > Here’s more detailed trace > > I’m redacting some things. > > mainlog:2023-05-09 13:49:51 1pwUHO-0005xx-1O <= username@domain > H=mail-lf1-f50.google.com [X.X.X.X] P=esmtps > X=TLS1.2:ECDHE-ECDSA-AES128-GCM-SHA256:128 CV=no S=8412 > DKIM=domain.20221208.smtp.com > id=CAMp+ihqPY0eLVsndLnN1pQxyO7_NT-TbRanQRwOpjdowwq2=k...@mail.gmail.com T="My > contact info" from for me@mydomain > mainlog:2023-05-09 13:49:51 cwd=/var/spool/exim 3 args: /usr/sbin/exim -Mc > 1pwUHO-0005xx-1O > mainlog:2023-05-09 13:49:51 1pwUHO-0005xx-1O SIGSEGV (fault address: (nil)) > mainlog:2023-05-09 13:49:51 1pwUHO-0005xx-1O SIGSEGV (null pointer > indirection) > mainlog:2023-05-09 13:49:51 1pwUHO-0005xx-1O internal problem in userforward > router (recipient is user@host): failure to transfer data from subprocess: > status=0100 readerror='No such file or directory' > mainlog:2023-05-09 13:49:51 1pwUHO-0005xx-1O == user@host > R=userforward defer (-1): internal problem in userforward router (recipient > is user@host): failure to transfer data from subprocess: status=0100 > readerror='No such file or directory' > mainlog:2023-05-09 20:16:14 1pwUHO-0005xx-1O SIGSEGV (fault address: (nil)) > mainlog:2023-05-09 20:16:14 1pwUHO-0005xx-1O SIGSEGV (null pointer > indirection) > mainlog:2023-05-09 20:16:14 1pwUHO-0005xx-1O internal problem in userforward > router (recipient is user@host): failure to transfer data from subprocess: > status=0100 readerror='No such file or directory' > mainlog:2023-05-09 20:16:14 1pwUHO-0005xx-1O == user@host > R=userforward defer (-1): internal problem in userforward router (recipient > is user@host): failure to transfer data from subprocess: status=0100 > readerror='No such file or directory' > paniclog:2023-05-09 13:49:51 1pwUHO-0005xx-1O internal problem in userforward > router (recipient is user@host): failure to transfer data from subprocess: > status=0100 readerror='No such file or directory' > paniclog:2023-05-09 20:16:14 1pwUHO-0005xx-1O internal problem in userforward > router (recipient is user@host): failure to transfer data from subprocess: > status=0100 readerror='No such file or directory' > > > > >> On May 9, 2023, at 11:00 PM, Robert Nicholson >> wrote: >> >> Furthermore can somebody please confirm that nothing in the .forward can >> create such an error? >> >>> On May 9, 2023, at 6:03 PM, Robert Nicholson >>> wrote: >>> >>> Here’s the full message that I’m seeing in the log file. >>> >>> failure to transfer data from subprocess: status=0100 readerror='No such >>> file or directory’ >>> >>> the exim binary does have +s >>> >>> -rwsr-xr-x 1 root root 1415656 Jan 7 06:47 /usr/sbin/exim >>> >>> exim --version >>> Exim version 4.96-58-g4e9ed49f8 #2 built 07-Jan-2023 06:47:04 >>> Copyright (c) University of Cambridge, 1995 - 2018 >>> (c) The Exim Maintainers and contributors in ACKNOWLEDGMENTS file, 2007 - >>> 2022 >>> Berkeley DB: Berkeley DB 5.3.21: (May 11, 2012) >>> Support for: crypteq IPv6 Perl OpenSSL TLS_resume move_frozen_messages >>> Content_Scanning DKIM DNSSEC Event OCSP PIPECONNECT PRDR Queue_Ramp SPF SRS >>> TCP_Fast_Open >>> Lookups (built-in): lsearch wildlsearch nwildlsearch iplsearch cdb dbm >>> dbmjz dbmnz dnsdb >>> Authenticators: cram_md5 dovecot plaintext spa >>> Routers: accept dnslookup ipliteral manualroute queryprogram redirect >>> Transports: appendfile/maildir/mailstore/mbx autoreply lmtp pipe smtp >>> Malware: f-protd f-prot6d drweb aveserver fsecure kavdaemon sophie clamd >>> mksd avast sock cmdline >>> Fixed never_users: 0 >>> Configure owner: 0:0 >>> Size of off_t: 8 >>> 2023-05-09 16:02:10 cwd=/var/log/exim 2 args: exim --version >>> Configuration file is /etc/exim.conf >>> >> > -- ## subscription configuration (requires account): ## https://lists.exim.org/mailman3/postorius/lists/exim-users.lists.exim.org/ ## unsubscribe (doesn't require an account): ## exim-users-unsubscr...@lists.exim.org ## Exim details at http://www.exim.org/ ## Please use the Wiki with this list - http://wiki.exim.org/

I am not the administrator of the machine so is there any way I can show you what you are asking for?

Also I am the owner of the .forward file but do the errors suggest anything is wrong with the .forward file? My understanding is the issue is before the .forward file is being processed but I could be wrong.

Definitely a bug; you should not be able to induce this by doing
something odd in a .forward.
For debugging it, it'd help if you could provide the matching .forward
rule (if there is indeed one), and even more if you could get a coredump.
The "failure to transfer data" log is a follow-on resulting from
the transport process dying (and not providing data) not ignore that.
Is the message successfully delivered on a subsequent queue-run
(grep the log for the message ID)? I see several failed tries in
the log extract you gave.
If not, and the message is still queued, please try forcing a delivery
with debug enabled ("exim -d+all -M 1pwUHO-0005xx-1O 2>&1 | tee debuglog")
