HOLD queue building up, not sure what to look for in logs.

[jdeverse]

Hello peers, I'm need of some dire assistance. I've got a new install of EFA, was working great. Then I disabled greylisting via the cli menu and mail started to build up in the hold queue. I've tried re-enabling greylisting with no effect.
I've updated to the latest version through the menu and have restarted several times.

The maillog is so busy with new incoming mail, I'm not sure what to look for to see what might be the issue.

Any help you can provide is greatly appreciated.

Thanks.

Ok, update, the system is processing mail, just slowly. I moved all emails out of the hold postfix folder and I've been planting them back in groups of 100 messages. The system seems to be processing about 2 email's every few seconds, so the backup seems inevitable under normal volume.

Looks to be resolved now, can't say I know what the root cause is. I think it may have been a corrupt file in the hold queue.

Hi everyone, I wanted to post here what I found if it helps others.
It all came down to disk speed on the system ,which was a KVM virtual. The bayes database portion was taking a good deal of time to process and root cause was the disk speed. I moved the vm instance to a disk with faster performance and the problem, which crept back this morning, immediately started to resolve itself. I still have a decent backlog at this time from the morning surge, but the system is now making progress against the hold queue instead of falling behind.
