Hi,
A second update for people who started to look at this issue.
I have identified the real cause of the problem by looking more in the kamailio log with the debug traces. I discover that it is related to the load of the properties table in the htable.
I have the following entries in my mysql db :
+-------+----------------+---------------------------------------------------------+------------+----------+
| id | key_name | key_value | value_type | key_type |
+-------+----------------+---------------------------------------------------------+------------+----------+
| 0 | VERSION | 120104-1734 | 0 | 0 |
| 1 | mmm-retry | 408=Y;502=Y;503=Y | 0 | 0 |
| 2 | mgcf-retry | 408=Y;502=Y;503=Y | 0 | 0 |
| 3 | max-mmm-retry | 2 | 0 | 0 |
| 4 | max-mgcf-retry | 2 | 0 | 0 |
| 5 | target-uri | mgcf=10.10.10.10;mmm-legacy=20.20.20.10;mmm=20.20.20.20 | 0 | 0 |
| 6 | pike-status | 503 Service Overload | 0 | 0 |
| 7 | mgcf-path | 99 | 0 | 0 |
| 16 | mmm-nodeid | OPMMMS1VSE01=1;OPMMMS1VSE02=2 | 0 | 0 |
| 17 | mmm-node-path | 1=1;2=2 | 0 | 0 |
+-------+----------------+---------------------------------------------------------+------------+----------+
In the kamailio.cfg, the << modparam("htable", "htable", "propertiesHash=>size=4;dbtable=properties;") >> command causes the load of the above table in the htable.
In the log we can see, that the load is done in the alphabetic order of the key_name and it fails to load the last entry "VERSION" :
Mar 21 10:25:28 localhost /usr/sbin/kamailio[5784]: DEBUG: <core> [db_val.c:169]: db_str2val(): converting BLOB [VERSION]

Mar 21 10:25:28 localhost /usr/sbin/kamailio[5784]: ERROR: htable [ht_db.c:276]: ht_db_load_table(): key type must be string (type=6)
If I add a new entry named "WWWWW", then the failure occurs on this entry that is the last alphabetic entry :
| 10000 | WWWWW | toto | 0 | 0 |

Mar 21 10:28:45 localhost /usr/sbin/kamailio[5817]: ERROR: htable [ht_db.c:276]: ht_db_load_table(): key type must be string (type=6)
Attached the kamailio log for each test.
I hope this help.
Have anyone an idea of this problem ?

Hi,
There was a mistake in the file attached ; the short kamailio.cfg file (that makes kamailio to start) was not the correct one; attached the correct one.
Have anyone an idea of this problem ?

Hi,
To figure out what causes this issue, I work to shorten my kamailio.cfg to contains loadmodule/modparam instructions for the htable module only.
My first attempt (see kamailio.cfg.ok) shows that the problem doesn't occur.
In the second attempt (see kamailio.cfg.ko) I add instructions previously removed from the original .cfg file. I have determined that, depending on the instructions that follows the "modparam("htable", "fetch_rows", 1000)" line, the "key type must be string (type=6)" error occurs or not.
In this ko file, if I comment out the following sequence, the error occurs :
modparam("htable", "fetch_rows", 1000)
#!!ifdef FIXED_ROUTING
#modparam("htable", "htable", "mbxrangeHash=>size=4;dbtable=mbxrange;")
#!!else
#modparam("htable", "htable", "abpqHash=>size=12;dbtable=abpq;")
#modparam("htable", "htable", "zabpqHash=>size=12;dbtable=zabpq;")
#!!endif
modparam("htable", "htable", "propertiesHash=>size=4;dbtable=properties;")
I hope my explanation is clearn and there are people who can help me on this problem that causes kamailio to not start.

Hi,
Now the kamailio installation is completed, I try to start kamailio but got an error on a modparam line.
By looking at the kamailio.cfg (with debug mode) it looks like the instruction is not correct :
modparam("htable", "fetch_rows", 1000)

[root at vm-vse02-siprouter1 ~]#
The documentation shows that fetch_rows is an integer :
fetch_rows (integer)
How many rows to fetch at once from database.
Default value is 100.
Example 1.12. Set fetch_rows parameter
...
modparam("htable", "fetch_rows", 1000)
So how to explain the first error.
Have you any thoughts on this case ?
