Thank you Henning, that was a good hint.
I've noticed that kamailio and my perl script (which is 
using Cache::Memcached) set the value in memcached somehow differently.

kamailio:
set 888_HA1 1 10800 32.
6fa22552ea04d443ab5864a7b3c2168c.
perl script:
set 888_HA1 0 0 32.
6fa22552ea04d443ab5864a7b3c2168c.

VAR_VAL_STR is 1.

I will investigate further.

Regards,
Dragos

ps: I will also subscribe to sr-users .

Hi Dragos,
 
(setting sr-users to CC)
 
Ok, If you’ve set this by other means you need to set the appropriate 
“Kamailio” type flag to the value as well, that Kamailio can parse it 
correctly. You can get the appropriate value if you grep for “VAR_VAL_STR” in 
the source code.
 
Your perl script function call should also export the appropriate flag setting 
from the memcache library function call, then just add it here.
 
Best regards,
 
Henning

The issue is that the module somehow does not evaluate the string variable
_from memcached_ as a string, it tries to evaluate it as integer. This
obviously fails.

Has this value set from kamailio or is this from some external application?
Then probably this application does not set the proper flags which kamailio
expects.

Henning Westerholt
