IMAP connections problem

[robertofv]

Hi.
For a few days the imap connections with the clients have been blocked and I have to restart the service to make them work again.
I didn't find errors in the event viewer and in the imap log only appears some warnings like this:

[Thread:8024]StreamXMLStoreIndexSerialiser::DeserialiseHook Elapse: 0
[4624] Send failed (error 10053). Size 55
[4844] Send failed (error 10054). Size 14

Server version is 7.63

Thanks a lot.

Hello,

I'm here to give you an update on the subject, because since this morning, I'm also experiencing the same problem. I also did some checks in the event viewer, but I didn't see anything wrong. So, I hope to have more answers here.

Thank you

Upgrade to the latest release and report back.

7.63 is like 5 yrs old.
