Hi Alston,
I'm sorry for the late reply. Are you still experiencing this error?
I've seen this issue before with another customer and the final resolution was to make sure the /etc/hosts file does not have the ipv6 BEFORE ipv4. Here is an example:
>> cat /etc/hosts
# special IPv6 addresses
::1 localhost ipv6-localhost
ipv6-loopback
ff02::3 ipv6-allhosts
192.168.180.31 abceccd01.sap.com abceccd01
192.168.180.34 abceccs01.sap.com abceccs01
192.168.180.35 abccrms01.sap.com abccrms01
192.168.180.30 abceccs01.sap.com abceccs01
10.36.10.5 abceccs01-nfs.sap.com abceccs01-nfs
The resolution would be to change the ordering. So the IPv6 section appears below the IPv4 section.
After that is done, perform the following to "reset" HLM.
1. Stop all browsers that have HLM pages open
2. Stop the Studio
3. Execute /usr/sap/hlm_bootstraps/<SID>/HLM/stop-hlm.sh –f
4. Check that there are no any left HLM processes
5. Go to /usr/sap/hlm_bootstraps/<SID>/HLM/param/
and rename all files except logging.properties
6. go to directory: /usr/sap/hlm_bootstraps/<SID>/HLM
and rename directory persistence
7 restart SAP Host Agent - as root: /usr/sap/hostctrl/exe/saphostexec
-restart
8. open HLM ui via browser:
https://<hostname>:1129/lmsl/HLM/<SID>/ui/
I hope this helps.
Best Regards,
Jimmy
