[Users] Re: [Devel] how to prevent concurrent calls per subscriber?

[Bogdan-Andrei Iancu]

Hi Raymond,

this is a runtime error. it means that you try to check via "avp_check" 
two avps which have different types of values (int and string).
my guess is that the problem is around :

avp_write("s:inuse","$intinuse");

if (avp_check("s:limit","gt/$intinuse/g")) {


avp_write will actually write the "s:inuse" string into $intinuse AVP 
and not copy the value (not sure which is the intention).

Use avp_print() before each "avp_check" to see the values (use debug=6).

regards,
bogdan
