New subject: pdb module timeouts

15 Feb 2011


      Hello,
I did a fallback to the original source, without sucess. I still have massive timeouts.  So far I have no idea,  how to go on.
ps. what lenght of the carrier codes would be ok ? 3...10 digits, additional characters needed like  A,B,C,D,E,F?
regards,
Thomas
Hi Henning,
this change was done at pdbt.c:
$ diff pdbt.c pdbt_changed.c
245c245
<               bufsize = slen + 1 + 1 + 3 + 1 + 1;                 // line buff
er (telephone number + colon + white space + carrier ID + newline + \0)
---
...
          bufsize = slen + 1 + 1 + 4 + 1 + 1;                 // line buff

er (telephone number + colon + white space + carrier ID + newline + \0)
257,258c257,258
<               ret = snprintf(p, 5, "%d\n", node->carrier);
<               if (ret < 1 || ret > 4) {
---
...
          ret = snprintf(p, 6, "%d\n", node->carrier);

if (ret < 1 || ret > 5) {
If I run querys in filemode against the server, where is no timeout.
pdbt query -f /tmp/numbers3 -r 10.12.18.21:10001 -q 1 | grep answer
regards,
Thomas

I am using the PDB module and server components for number portability. 2
instances of PDB Server runs on (10.12.19.51/10001/10002), Kamailio on
(10.12.19.21). With a small amount of traffic (-cmax 150 -cps 10
-callduration 3), where are timeouts: WARNING: pdb [pdb.c:260]: exceeded
timeout while waiting for response.
One requested number was 307111094, where the module prints out a timeout.
The funny part is, that I can see the responses at least arriving at the
10.12.19.21 interface on time.
Request send: 0,200855 s
Answer received: 0,201027 s
That are 0,172 ms and far away from a timeout.
What could be the reason ?
Hi Thomas,
a bit difficult to say on a first sight.. Maybe some scheduling or load issues 
on the local machine? I've just checked two production server here, i don't 
see it so far in the available logs.
How much load do you've on the machine? And what kind of timeout value do you 
specified?
...
ps. A small change on the server part was done: handle 4 digit carrier
codes. 
Ah, i see. I guess its not a big change?
Regards,
Henning
