CARMLS Rets Feed Hangs

Every night we pull the statuses of all listings for each MLS we serve to clean up missed data. When I try to pull all the Residential listings for CARMLS, it hangs right about 100,000 listings (after about 1 minute). We haven't had this issue in the past. Is there possibly a problem with the underlying database?

My last failed attempt was about 11:04 CDT Thanks, Paul Stallings

Thank you for the details, Paul. We'll begin reviewing.

Can you try this again and see if it works now?

Well, a tiny improvement. I'm pulling in 5,000 record chunks. It was failing when running a query with a 95,000 offset. This time it hung with the 100,000 offset. It's supposed to return 112,000 some odd records. But it's still hanging.

Are you using RETS Connector?
If so, on the General Tab, set the HTTP Timeout value to a larger value and see if it works then.

No, libRets. We pull much larger result sets than this with no problem. I don't even get an error. It just stops. It was waiting for more than 5 hours last night.

I have duplicated the issue issue and we are working on a fix. Property
RS_1
(L_AskingPrice=150001+)
L_ListingID,L_UpdateDate,L_Status,L_PictureCount,L_Last_Photo_updt,L_ListingDate
Offset: 100001
Limit: 5000

Please test this again today to see if you are still having issues with this?

Sorry Bruce, I replied to the e-mail I got this morning and didn't notice it was going to "no-reply". Looks like things are fixed. That job that has been getting hung wasn't this morning so I was hopefull. I just ran the AllListings search and saw that it is no longer hanging. I did notice that we had split this search into multiple smaller searches some time in the past (L_AskingPrice=150001+ and L_AskingPrice=150000-) presumably to get past a similar issue in the past. I'm guess that due to raising house prices, our 150001+ search was now returning more than 100.000 record ceiling we were seeing. Can you tell me what you changed? Hopefully it means I can remove these hacks we put in in the past since I forgot to look for them this time.

I would just monitor it this week and see how it does.

Hi Paul,

We've released a fix. Please verify your original query is working.

@pstallings You can also try removing your workarounds and see if it works reliably and quicker without it.

Worked fine. Actually, it's been working fine all week. I think it no longer has a short pause at 100K. Will this change effect our other Paragon RETS feeds? I think we had similar tricks to break queries into smaller than 100K chunks elsewhere. I'll try simplifying our queries when I get a breather. Thanks!

Thank you. We had put a temporary fix in place, but released a permanent fix, so we wanted to make sure it worked.

It was a stability fix. If you weren't having this issue with them, then I wouldn't worry about it. If you did find an issue in another system, this fix will be deployed early next week.

@pstallings The fix has been deployed to the remaining Paragon RETS servers so you can try removing your workarounds a little at a time and see if it performs better with the fix.
