Excessive CPU Usage on on build 8545

Problem reported by Jade B - 5/31/2023 at 10:22 AM

Submitted

Just finding out if there are any others on here that have experienced high cpu usage on the latest build of smartermail, and if so what to look out for?

Thought I would ask whilst we dig through the logs

pftop on dc firewall shows only 100 or so connections to this server now (after hours) so hardly and issue with overload, cpu stats below

logs below seem consistent with excessive cpu usage

Hi Jade, I'm sorry to hear you're having issues with high CPU. I recommend we get a ticket submitted on this one to look for any signs of trouble. I can create the ticket for you today and will reach out here shortly to get the ball rolling.

Hi Kyle,

Thanks for reaching out, will create a ticket tomorrow morning (it's past 20H00 here now).

Still checking on my side to see if I can narrow things down.

We're seeing this issue as well.

Right after upgrading to build 8545 we saw highly increased CPU, RAM and disk usage with lots of CPU peaks at 95-99% which we didn't have before.

Use windows resource monitor to drill down on the disk activity, this may give you insight into what is going on, ie it could be the indexing service that is re-indexing your users mail boxes after the upgrade.

CPU usage seemed to normalize in the early hours of the morning so I'll monitor this to see if there is a repeat and if so log a ticket, interestingly at the same time spool grew and mail was not being processed.

We're seeing something similar. Did you ever figure out what was causing this and get it resolved?

Thanks.

It seems to be URIBLs filters. Resolved in 8587

We're still see excessive CPU with Build 8587 (Jul 6, 2023). Not using any URIBLs filters.

Then it must be some other problem... Luckily my server is back to CPU and RAM usage at quite low levels after upgrading to 8580 and then to 8587...

Always a little more than the "old" SmarterMail, but nothing to worry about, so unfortunately I don't know what other advice to give you...

We have a serious problem with excessive CPU usage in Build 8587 (July 6), we didn't have this problem in previous versions.

We disabled the URIBLS and also several RBL to be able to work again.
