Re: Since Upgrading To Zimbra 8.8.5, Have Been Getting Numerous Lock Errors

davidkillingsworth, from your description, you might be seeing a different problem than what this thread is about. I don't recall seeing high CPU usage or slowness when this problem happens, what I do see is many users unable to login and access email. In your mailbox.log, do you see tons of "...

Re: Since Upgrading To Zimbra 8.8.5, Have Been Getting Numerous Lock Errors

Rebooting once a day isn't enough. I tried twice a day (7AM and 7PM) and that wasn't even enough, eventually it failed around 6PM one day. Now I'm doing three times a day and seems OK so far. Also, our server isn't even that big, about 60 mailboxes (although I'm not sure if this problem is traffic/u...

Re: Since Upgrading To Zimbra 8.8.5, Have Been Getting Numerous Lock Errors

Support told me that engineering is already working on it, and they didn't seem to need/want any information from me other than my zmdiaglog to confirm that this was the issue I was experiencing. The official workaround for now is to restart your server frequently... Please let me know your Support...

Re: Since Upgrading To Zimbra 8.8.5, Have Been Getting Numerous Lock Errors

Been running into this, too, after upgrading from 8.6.x to 8.8.5. Happy to help debug if you tell me what to look for. I've got a small site with very few users so I can take it down on a whim to test stuff. Support told me that engineering is already working on it, and they didn't seem to need/wan...

Re: Since Upgrading To Zimbra 8.8.5, Have Been Getting Numerous Lock Errors

Upgraded from 8.7.11 to 8.8.6 and now having this problem. Mail server only works for about 24-36 hours before going berserk with this stuff. Have a support case open right now, but no solutions yet. Not sure how they aren't already on top of this massive problem, given it's been posted here for wee...

Harden ZCS Spam Filters

If you use reject_unknown_client_hostname, you will undoubtedly reject some legitimate email servers that are poorly configured. On the other hand, reject_unknown_reverse_client_hostname will still catch a lot of spammers, and is near 100% safe to use. All depends on how aggressive you want to be, o...

re: the DCC build error, it would seem that you don't have the C compiler installed on your system. You'll need to rectify that first. DCC's pretty worthwhile in my experience, so I'd spend the time to get it working. Also, local.cf is the wrong place to put your custom SA rules. The...

Upgrade 8.0.7 to 8.5.0, RHEL 6 - Successful?

I have several support tickets open reporting various bugs in 8.5.0. I've been using Zimbra since 4.x, and I upgrade to each new release. I've never had to report more than one bug against a specific release in the past. Here are some of the bugs currently present in 8.5.0, most of them have...

Sorry, meant 8.5.0 of course (not 8.0.5...)
