[SR-Users] ht_db_load_table(): key type must be string (type=6)

[Ginhoux, Patrick]

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)

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 ?
