Clamd hanging or stopping unexpectedly

[drewmorris]

Has anyone else had issues with clamd just stopping on their EFA installations? I have been experiencing an intermittent issue where clamd just stops responding and mail will queue up in the HOLD queue and either never be delivered or sit there for hours before it is delivered. Does anyone have advice on how to address this? Its hard to detect until the queue fills up to a certain level that would alert me via monitoring and I just don't understand why it would be happening.

This is fairly new EFA install (about 3-4 weeks old) but I have seen it on an older one I have in my testing environment once or twice as well.

Mostly you will see this issue if there is a lack of memory.

Before you try any furture troubleshooting try to increase the memory the ammount needed depends on your workload so hard to say with any details.
The bare minimum is 4GB, but if you already have these issues and already run with 4 GB try to double it to 8.
