Dear all,
we have an OTRS installation (version 3.3.5) running on Ubuntu 12.04 LTS and Apache 2.2.22. Usually once a day (sometime more than that) it stops sending e-mails - for example, when an agent replies a ticket, it hangs and never comes back.
To solve it we have to restart the apache server.
No error message is recorded in the log files.
Any ideas?

Re: Hanging when sending e-mail
Regarding DNS, could you elaborate? Since it hangs eventually (not all the time) the DNS is working.crythias wrote:dns. top. smtp. syslog.
Regarding top, nothing strange - no process has high CPU usage or is in zombie state when this happens.
About SMTP, could you elaborate?
Regarding syslog, no erros/anormal messages. Nothing is recorded.

Re: Hanging when sending e-mail
Just as a feedback, I've turned off CheckMXRecord and it seems to have solved so far.

CheckMXRecord relies on DNS. However, if you're relaying via smarthost, it may not make sense to look up email MX records before sending it to an MTA that relies on DNS/MX records to send.keitarobr wrote:Regarding DNS, could you elaborate?
