[OpenSIPS-Users] Is RPID being cached?

[Alan Frisch]

Using OpenSIPs 1.6.1 and have noticed a peculiar issue.

If a subscriber has a value in the RPID column, then that value is
changed to NULL it seems that OpenSIPs still retains the previous
number.

For example:

If RPID column is NULL (initially) ---> if ($avp(s:rpid))) returns FALSE
If RPID column is changed to eg. 1234567890 ---> if ($avp(s:rpid))
returns TRUE and is 1234567890
If RPID column is then changed back to NULL ---> if ($avp(s:rpid))
returns TRUE and is 1234567890

Is this a bug or a feature?  In either case, is there a way to get
OpenSIPs to only use the current DB value?

Thanks!
