Hello All,

There is frequently crash issue on Traveler server due to error Message PANIC: Invalid pool free chain therefore IBM has prepared HF to fix the same and needs to be install on FP9.

on 31 Dec 2017 we have installed FP9 and installed HF provided by IBM however after that we can see none of the Traveler servers in HA pool therefore we have un-installed FP9 along with HF however at the moment nothing is working for us , we have raised Severity 1 PMR with IBM 33552,300,624 however we are not getting and response from IBM as well from SWAT.

So far we have done below steps however no success.

  • uninstalled FP9 as well HF on 2 Traveler servers out of 4.

  • We have 4 Traveler servers however no server in HA pool

  • We have re-added servers from HA rebooted all servers at OS level ,checked with Network and SQL team however nothing found any wrong.

We are now facing issue since long time and not getting proper response from IBM even raised Severity 1 PMR :frowning:

your help would be highly appreciated.

kind regards,

Mahesh Dhuri

Subject: I don’t deal with Traveler much.

It sounds like behavior after removal is different from behavior before removal.

Maybe install 9.0.1 again? Don’t kill of actual DBs, just run over the thing.

Also a check for later DLLs from Notes, and any tweaking y’might have done with certs are in order.

No system-level backup before this hotfix?

Start with the basics, check your servers can communicate with each other : ports 50125 and 50126 between the servers in HADR mode. And if you are sure they do because it was working before, TELNET is your friend. You never know some server’s local firewall might have been activated somehow
