Thanks, Jeff. The release containing the fix for this assert error is now available in all regions (as of yesterday afternoon). Appreciate if you can confirm that after upgrading to a release version >= 1.0.1636, the issue is resolved.
Thank you for bringing this to our attention.
Can you confirm if retrying the query allows it to succeed?
Hello,
Same error here using BIME a Business Intelligence report software.
The strange thing is that this error started occurred recently ~1 week especially when we add filters to the query.
A simple re-run of the query seems to fix it but it's quite a problem since the error appears randomly.
Hello @joeharris76-AWS ,
It is exactly what RonanTreillet answered:
"A simple re-run of the query seems to fix it but it's quite a problem since the error appears randomly."
Sorry you've experienced this problem. We have identified the issue and are working on a fix.
Please look for the fix to appear in our biweekly maintenance announcements at the top of the forum.
Hello,
Are you still working on the fix? The problem listed above remains, and I guess the next biweekly maintenance announcement will be on 14th december, right?
Any update on the subject ?
The problem still occurs and it's start becoming quite problematic for our clients.
Any updates on this issue.We have been getting assert error intermittently.Any resolution is much appreciated.
Thanks for reporting the issue. The assert error comes from a race condition during the processing of a query and that is why some users are encountering this intermittently. We have a fix for this issue and it is expected to start rolling out in a few weeks. Once a version number for the release containing the fix is confirmed, I will post it here for your awareness.
If you are experiencing significant pain due to this issue and waiting (about 10 business days) for an official patch to roll-out impacts your workload, please send me a private message and we can explore the option to private patch your cluster with the fix.
The fix for this issue has been deployed on Jan 11, 2018, please see the release announcement here: https://forums.aws.amazon.com/ann.jspa?annID=5358
If your cluster is on a build level that is 1.0.1636 or higher, you should no longer encounter this issue. If would be great if someone can validate their scenario against this build level.
Thank you.
Hello,
Our Redshift cluster is still on version 1.0.1582
Our maintenance window is Wed. 8:00-8:30
Is there any way you could patch our cluster this week?
We've been having a lot of errors lately while running our data pipelines, which we hope will get solved by this patch.
error: Assert
code: 1000
context: p - id=334 not in rowsets list
...
Thanks for your help.

Hi Jeff,
What region is your cluster in? If you private message me your cluster endpoint, we can check when the patch with the fix will be available for your region.
In case anyone is having the same issue and wondering about the timing of patch updates...
The updates are rolled out by region.
I'll update the post with results of whether we're still seeing the assert errors or not once we get the patch.
Thanks for your help Naresh.
Best,
-Jeff
The us-east-1 region will get the patch with a fix
this Thursday by noon Pacific Time. If you change
your maintenance window to Thursday evening, you will
get the fix in a couple of days.
Hi Naresh - just looking at this thread as we had an assert error begin to pop up on Friday 1/26, and am wondering if it's related to this (or possibly even triggered by the fix). We've gotten two variations in the error:
"error: Assert
code: 1000
context: mod == -1 || (mod - VARHDRSZ) == size -"
and
"error: Assert
code: 1000
context: val->len <= maxlen -"
I've confirmed that I can run the relevant model in a SQL client but it will not run as part of our scheduled process (ran completley fine until 1/26, with no changes since). Please let me know if you're able to assist!
Hi Mike,
Based on a quick look, this new assert seems unrelated to what was originally reported in this thread. Could you please do one of following:
- Open a support case with all pertinent information for us to investigate this error
- Start a new forum post to discuss this
With either option, if you can provide us with the relevant DDL and the query so we can reproduce the problem in the lab, that would enable us to investigate and try to provide you with a workaround to avoid this issue.
Thanks.

Hi Naresh,
Yes the patch is definitely working and seems to have fixed all the assert errors we were seeing before. We just ran about 60 pipeline jobs over the weekend and none of them produced the assert error. So it looks like this particular issue is fixed.
error: Assert
code: 1000
context: p - id=334 not in rowsets list
Cluster Version
Version number of Redshift for this cluster. 1.0.1657
Thanks for your help.

I solved this by materialising the upstream views as tables and then selecting from them.
It's a bit of a bandaid but worth a shot.
