Strange behaviour: summary reports purple while test details is OK 🔗 link

Good day! 
We had renamed 2 hosts today and renamed all (I hope) at host level and in XyMon config and restarted XyMon server and clients too.
Rename in XyMon was done as:
a) changes records in hosts.cfg
b) xymon 127.0.0.1:port  "rename OLD_HOST  NEW_HOST"

the same server - generates normal reports for 2nd host renames

We have 2 XyMon server for High Availability and clients send info to 
both.
The 2nd XyMon Server (4.3.4) - generate normal reports for both renamed 
hosts.

So, question N 1 is - how to find where is the problem?
This only thing I had found in info report (which with trends are always green by the way) is that different status for the same metric is reported with minimal interval delta (~ 10 min which may be time since hostname change and xymon client restart and when "rename" was called at XyMon 
server.
For example:
Status summary:

purple  msgs Mon Jul 08 13:59:44 2013 0 days, 05 hours, 12 minutes

This mean XyMon counts summary for 2 hostnames - new one (with info received just after hostname rename)  and old one, but renamed to new 
name.

By the way, I had found on both XyMon servers there are still directories for old nad new hostnames under xymon/data/hostdata/
old host data not updated any more, but new ones only. Question N2: Is it expected or after  xymon "rename ... "  call all should be merged into one directory per host?

At last I had found solution myself:

stop XyMon both on client and server
and remove all files under XyMon tmp directory:
alert.chk
alert.chk.sub
xymond.chk and others 
I am not sure which exactly file was wrong ( I suppose it was xymond.chk on server), but now it is working.
The only backside effect - all metrics status last change time reset
so all metric images are with "round"  smiling gifs.

Rename in XyMon was done as:
a) changes records in hosts.cfg
b) xymon 127.0.0.1:port  "rename OLD_HOST  NEW_HOST"

Now XyMon Server  (4.3.11) - generates purple for 1st host in non-
green and group reports while every test details shows green, > yellow, red and so on what is expected.

the same server - generates normal reports for 2nd host renames

We have 2 XyMon server for High Availability and clients send info to 
both.

The 2nd XyMon Server (4.3.4) - generate normal reports for both renamed hosts.

So, question N 1 is - how to find where is the problem?
