RN4220 / Ver6.9.2 - File Access Not Possible / "clamd" CPU usage on the NAS 99.9%
Dear Netgear Community, we are an experiencing a problem with one of our customer's NAS and I was hoping you could help us. The Model and Firmware version are as follows: RN4220 / Ver6.9.2. The probl...
You are a litle behind on updating your OS version, and the release notes for 6.9.3 include this:
Bug Fixes:
- Fix AV to prevent strange behavior
- Fix AV update pattern
So, I recommend you update to at least 6.9.5 and see if that doesn't fix it.
Thanks for your prompt reply Sandshark. I will try upgrading the firmware on our test environment and see if it resolves the problem. Regards
Dear Netgear Community. I originally said the Firmware version on the NAS experiencing the problem was 6.9.2, but, I have confirmed since then that it is actually 6.9.4. We have several customer offices using the RN422 and they all run Ver6.9.2, except for one of our customer’s RN422, which uses 6.9.4, and that’s the one the problem accessing the NAS is occurring.
Since 6.9.2 has been stable at all the offices we are using it, we feel it might be safer to downgrade the Ver 6.9.4 NAS to Ver 6.9.2, rather than upgrading to the unknown (for us) Ver 6.9.5 (and easier to convince our Ver 6.9.4 customer to downgrade to conform to the other office’s versions).
I would like to confirm, is it possible to downgrade from 6.9.4 to 6.9.2, and, is the 6.9.2 generally stable to use? I looked at the release notes for the various versions, and it seems that 6.9.4 was particularly problematic, but that 6.9.2 was ok. Does anyone have any experience with 6.9.2 or any advice on this? I really appreciate your input. Best regards
Other than one "sandbox" NAS I have, I am never a first adoper of firmware updates. I, too, stuck with 6.9.2 for a while, since I saw problems reported here on 6.9.3 and 6.9.4. I finally switched to 6.9.5 ten months ago when it seemed stable (which was after a couple of "hot fixes" for it, I believe). Here is the tail end of my update log so you can see how careful I am:
- [2018/01/30 01:35:38 UTC] Updated from ReadyNASOS 6.8.1 (ReadyNASOS) to 6.9.2 (ReadyNASOS).
- [2019/03/09 18:24:39 UTC] Updated from ReadyNASOS 6.9.2 (ReadyNASOS) to 6.9.5 (ReadyNASOS).
This is on an RN4200V2 converted to OS6, which is a 12-bay rack-mount system that is very similar to your 4220 (it's the last rack mount of the OS4.2.x family and yours the first of the 6.x). Of course, I don't run AV on it either, since I have control over everything that goes on it.
The only downgrade warning for 6.9.4 is Devices updated with 6.9.5 firmware should not be downgraded to firmware versions before 6.9.0, so go whichever makes you more comfortable.
