Hello
I am having an issue with Postix 2.11 crashing multiple times per day with
the following errors:
Feb 13 21:28:37 mail postfix/master[5828]: warning: process
/usr/local/libexec/postfix/smtpd pid 14469 killed by signal 11
mail postfix/master[5828]: warning:
SW:
Can someone assist me with troubleshooting this further please? I have been
through the logs but I can't find any clue as to why this is happening.
I'd be happy to answer any questions about my main.cf or master.cf file.
What other warnings does Postfix log?
Hi Wietse, many thanks for the reply.

I have removed the -D flag and restarted Postfix. I will keep my eye on it
and report back.
I'm really hoping for an email to come from Ebay and/or Facebook as that
always caused a signal 11. I'd like to see if removing zlib resolved that
issue.
I really appreciate your help

In that case it would be prudent to log what happens:

Is message_size_limit still valid? All of the references I can find
to it online are very old. Is there another postfix directive I
should use to set the maximum upload size for roundcube?

Am I correct in saying that removing the -D from master.cf will prevent
Postfix from stopping again?
Whether it does or not, you should not run with -D in production.
I've been running fine for about 3 hours since removing -D and removing zlib
from OpenSSL. I think its still too early to tell for sure if everythings
ok.
I will check the logs again tomorrow morning to see how things look.
I really appreciate both your help (Viktor and Wietse) very much!

I can't see the -D option anywhere in my master.cf file. I think this issue
was occurring before trying that anyway. I have also restarted the Postfix
service.

I expected this to timeout as I don't have internal DNS name

Yes, you are correct. That is the cause of the problem. A quick entry of my
machine in the hosts file sorted that one out!
I'm just baffled why I have never experienced this issue before.
Thank you everyone.

Your problem was with zlib/openssl, and you have a solution for that.
The -D option is for trouble shooting. You never use it for normal

I understand. It was more an FYI.

it's not being filtered on my email client. In fact, in testing, I shut down
