F5 LTM 11.5 : SYNC FAILED after applying iapps

Hi,

I had the same issue.

To fix this I restarted the Device Trust in both units, then I did an upgrade to 11.5.1 HF4 from 11.5.1 (without a Hotfix) and then rebuilt the cluster.

Hi,

also same issue "Database error (13), Can't save/checkpoint DB object, class:sflow_http_virtual_data_source status:13 - EdbCfgObj.cpp, line 127." on the passive LTM node. Configuration synchronisation was broken.

After the passive device reboot with the mcpd forecereload procedure, the configuration synchronisation between actve and passive was restored but HA was broken (both nodes wanted to be active).

In fact, the port lockdown of my failover interface has switched to "Allow None". Setting the port lockdown back to its previous value has fixed this second issue.

BIG-IP 11.5.0 Build 4.10.245 Engineering Hotfix HF4 resolved my issue but I had to call in for this release.

Hotfix-BIGIP-11.5.0.4.0.245-HF4 was released. did you mistype that 1 in your build number or is that a patch to HF4 ? I am on HF4 (4.0.245) currently and have not seen the issue recently.

No. I experienced this issue on 11.5.0 Hotfix 4. Once I was provided the Engineering Hotfix HF4 (4.10.245) I cannot replicate the error.

There is also a "post" HF4 engineering release for 11.5.1, that I'm still testing.

We ran into this on 11.5.1 HF4 as well. We need the engineering hotfix soon...

Hi everyone, I own active/passive LTM 3900 with 11.5.1 HF4 and I went through the same error ... Except that I never ever used iApp features ... It's not only about Synchronisation, this also happens on the passive device :

Loading configuration doesn't work at all either.

I opened a support case, I'll let you know what's next

FWIW, I saw this issue in 1.5.1, but after applying hotfix 4 I haven't been able to recreate it. I am creating an iApp through a scripted SSH process.
