IMAP/EXIM timeout errors - dovecot

[Kyle]

Hi,


I have been getting a lot of alerts from my email server. I have managed to track down that it is something to do with EspoCRM reading the accounts. I have no idea what I can do about this. Any help or suggestions would be greatly appreciated.

Here is what I have been able to find in the logs:

exim [TCP Transaction Log: << 220-ded.***** ESMTP Exim 4.93 #2 Mon, 24 Aug 2020 09:56:07 +1000 Timeout while trying to get data from service: Died[check command:+][socket connect:-][socket failure threshold:3/3][fail count:1]Restarting exim....

Hi Kyle,
Do you use CPanel? It looks like your problem is related to one of the following issues:

Thanks Maximus
I am using CPanel on Cloud Linux.
I did not have CpHulk enabled, I did enable it late yesterday as part of my server setup and interestingly enough I have not had an error since. Normally I would have expected a few in this time, I will monitor the situation and see what happens. I will update the forum when I know if its fixed.

Its been almost 48 hours and I have had no more errors. It would appear something to do with CpHulk was causing this however it is not clear what.
I enabled CpHulk and then disabled it and have had no more errors.
