Hi,

Couple of days ago I've upgraded my prod environment to 1810. Everything was smooth and all is working fine.

However, there is one thing that starts to bother me a lot.

Content Distribution to all my DP's is taking a couple of hours where it took a couple of minutes in the past.
It is normal that it takes long to some remote DP's. But it's taking hours for all of them. Even those located in HQ.

A small package of 10MB took a minute or two in the past to be fully processed and now it takes a couple of hours.

As an example, some package are still synchronizing since yesterday.

I have no bandwidth limitations on any DP.
The thing is... eventually it works fine. But it just takes very long.

It worked perfectly fine for years. Never had any issues with it.
Any idea how to start troubleshooting this?

In the PkgXferMgr.log file this keeps coming back:
Yield 5 seconds due to bandwidth control, the current sending rate is 50 percent

But I have no limits on my DP's?
Is there another place this is configured other than the DP "Properties\Rate Limits"

I think the only place to limit the bandwidth used by DP is "Properties\Rate Limits".
If you are using a distribution point group, check their properties too.

Well, that's what I thought.
I have none set, except for one DP.
But it's required on that particular DP.

If you run this query on the SQL Server it will show you if any DP has bandwidth throttling:
SQL: 
Select * From SC_Address

I'm not sure which options you referring to in the DP Group properties?
I don't think there are any bandwidth settings in the DP Group properties.

Having similar issues since deploying 1810... content distribution and clients discovering new apps is taking exponentially longer then before. It's very frustrating.

That is so frustrating. I'm noticing the same issues.
I can't seem to find any solution for it.

What kind of environment do you have, CAS, Primary, Secondaries. Can you zip and send me the log files - Sender.log, despooler.log, distmgr.log and pkgxfer.log from the site server via contact form.

In my case, the issue was in the Database. Per the MS Engineer, there were some left over tasks that were flooding the smsdbmon.log file. Since those tasks have been removed, everything is working much better.

I'm awaiting the full write up, once I get that I'll try to provide more details where possible.

Here is the write up from MS Support ... hope this helps someone else.

------

we sent a test package at 1:32pm, but distmgr didn't process it for another 20 minutes

This was because smsdbmon log was just full of tons of these errors every second

The triggers listed below are the following ones that we needed to delete

Collections_L table:
SMSDBMON_Collections_L_PolicyTargetEvalNotify_iud_ins
SMSDBMON_Collections_L_PolicyTargetEvalNotify_iud_upd]

Collection_MemberChg_Notif:
SMSDBMON_Collection_MemberChg_Notif_PolicyTargetEvalNotify_ColMember_iu_ins
SMSDBMON_Collection_MemberChg_Notif_PolicyTargetEvalNotify_ColMember_iu_upd

PolicyAssignmentChg_notify:
SMSDBMON_PolicyAssignmentChg_Notify_PolicyAssignmentChg_Notify_iu_ins
SMSDBMON_PolicyAssignmentChg_Notify_PolicyAssignmentChg_Notify_iu_upd

We also checked registry under HKLM/Software/Microsoft/SMS/Triggers to see if there were any related entries to the triggers we wanted to delete, but there were not

So once these were deleted, we created a new package and did a distribution and it finished in under a minute, success!

Hello Daptonic,

I am experiencing the same issue after upgrading to CB1810 yesterday. Did you receive the full write up from MS Premier yet?

I posted a write up, but it is sitting in a Moderation queue. I'll PM it to you.

or not ... I don't appear to have the rights to do that either lol

Hello,

We have been having the same problem with our DP. It takes up to 24 hours for files to come down to the DP's and these files are not big files. We are talking say script that is approx 10k. The only way we can possibly accelerate the process is to restart the SCCM Services. We are running version 5.00.9068.1000. Waiting 24 hours isn't an option and having to restart services any time we update a package isn't feasible either. Any help would be appreciated.

Hi Rankinf,
As I remember the problem in ny case was an error in the particular update. The update made all our 12000 client update at once even though configuration was set to use 7 days. Our MP’s got overloadet and therefore it took long time to update distribution points.

Hello,

Well, we only have one DP for the college as we only image machines as needed and update the images as software's need to be patched. This is why its confusing that it is taking 24 hours to just push a single update to the single DP. Further more, the DP is the SCCM server itself.
