Logrotation Email not working after Update to Plesk Onyx

[mvais]

Hi,

One of our customers uses the email feature from logrotation. Here's a screenshot of the current settings (sorry it's german). The rotation is set to weekly. The rest should be clear.

Since the update to Plesk Onyx the following processes are spawning and stay forever. The emails aren't send to the customer. The following output ist cut from bash command (it's around 50 times those 3 processes): ps axjf

This specific server runs CentOS 6.9 with Plesk Onyx Version 17.5.3 Update #21. Installed Mailserver: QMail / Courier-IMAP

On another server with same OS and Plesk we couldn't reproduce this problem. But so far we could reproduce this on one other server with CentOS 7.3 and Plesk Onyx Version 17.5.3 Update #21. This one uses dovecot instead of Courier-IMAP.

So far I have no clue where the problem may come from.

I don't know if the following output of lsof helps but maybe it's useful for someone.

Is the destination mailbox ready to receive mail from the sender? Does it have enough storage space and is is accessible on or from the sender's server?

 

[mvais]

Sorry, I was out of office yersterday.
Yes the mailbox is ready and it did received emails till the day of the update. At the moment the mailbox uses around 700MB of unlimited. And the server has 45GB free disk space. The mailbox is a "normal" plesk mailbox on the same server.

 

[mvais]

Any hint for me? Can i provide more information?

 

[mvais]

I noticed that the problem disappeard on one of our servers. Looks like the Update #22 from 18.9.2017 fixed it. But I didn't found anything in the patch notes. After installing the update on the other server the problem also disappeared.

I was wrong the update didn't solve the problem. After the Update our first testmail went through but this weekend serveral new processes are stuck and the mails didn't get through.
