ok maybe its because we just restarted exim and its still off so PID cant open file, that's why it says (Yet?) : Can't open PID file /var/spool/exim/exim-daemon.pid (yet?) after start:

just making sure never noticed this before

thanks again in advance

I was looking specifically for an advanced configuration in which exim was requested to listen on specific ports - in older versions folks were having exim listen on ports it already listens on and while it functioned in previous versions, it causes similar behavior with exim.

When you restart exim every time does this occur or it was just the one time?

Not sure if it's just adding this to startup log because it's in-between restarts ?

or if it's really an issue?

So what it seems like is happening is that exim is taking a while to restart - This is why when the PID is looked for it's not being found immediately. It is restarting though, and then it is running. Is the load on the server high or resources constrained at all?

Hi sorry for the late response but the answer is NO load is normal and not constrained. but it does restart, just was wondering why.. have you been able to verify that on your server it does the same ? i install server VPS CentOS 7 Fresh Install cPanel 84.06 and now I have upgraded to 84.08 and it still does this.

if you can replicate this on a server then its as you say it is, if not maybe an issue on my vps for some reason ?

How long does restart take?

Maybe 1-2 mins. I am going to do a fresh install of cPanel on a fresh install of CentOS 7 vps and will see if I get the same error. Maybe it was the first build if cPanel will repost in a little bit with the outcome.

 

[Spirogg]

I do not get the same behavior when restarting exim:

Fresh Install on CentOS7 using upcloud service, created new cloud server Stopped and disabled NetworkManager, then installed cPanel using command line from your website

Logged into WHM enabled Quotas, restarted server Gracefully. Logged back in and clicked restart Exim.. also tried restart exim from command line, and I still get the same log error

i went to /var/spool/exim/ and there is a PID file located there

/var/spool/exim/exim-daemon.pid




This is the same issue with new install of cPanel 84.08

Really Weird
latest version of cPanel that got installed was 84.08 fresh install

thanks again for the help @cPanelLauren

 

[Spirogg]

hi @cPanelLauren just FYI..

ok I did some testing and tried a few other configurations of vps servers in the cloud,

the one I have is just 1 cpu 2 gm ram, it always does this,


the second was 2 cpu 4 gb ram this server was intermittent first it does it then i restart again and it doesnt


the third server was 4cpu 8 gb ram and it never showed this, no matter how many times i restarted exim.

So I am starting to think its the server ram that creates this issue, the less cpu and ram you have the longer it takes to restart and maybe that's why

not sure if its worth the trouble of trying a few different configs on your own cloud servers if you can to verify

Thanks

Spiro

Hi @Spirogg

Yea, 1-2 minutes is a REALLY long time for exim to restart and would definitely explain why thats occurring.

So I am starting to think its the server ram that creates this issue, the less cpu and ram you have the longer it takes to restart and maybe that's why

This is a result of the amount of available resources on the server, the less it has to work with the longer it's going to take to process a request.

 

[Spirogg]

@cPanelLauren

Yes that is the issue. If you have anything less than 2cpu 4gb ram it will throw that warning always. If it's above 2cpu and 4 GB ram it doesn't throw that error.

We can mark this as solved.
Sorry for the headache and thanks for all the help

Warm regards,
Spiro
