Please disregard this. I was incorrect about the source of the error message. It is coming from a log statement we have where we are attempting to print the contents of an AVP as a list. In this case the list is quite long and is causing the buffer exhaustion.

This error prints from multiple places in the code and we were not able to isolate the source until now. I have been able to consistently reproduce the error by calling avp_insert. It seems to happen every time I call it in a particular place, but I cannot identify the cause of the buffer issue. Logs from an occurrence are here: https://pastebin.com/HvmrXqii The relevant section of my config script is here: https://pastebin.com/301U1yY2 I am currently running 1.11.11, which I know is unsupported. But I am trying to determine whether it is an OpenSIPS issue or whether I am using this function in a way that is not intended. I am trying to use it to push values onto the end of an AVP stack. According to the docs [1]: “If the index is greater than the count of values the value will be inserted at the end.” So I have selected an index that is known to always be greater than the number of elements (32) and am performing the insert at that index. I must do this because there does not seem to be any way in OpenSIPS to determine the number of values in an AVP except to traverse the entire list. I attempted to keep track of the number of items in the destination list using another variable, but avp_insert will not accept a variable as the index argument, only a number. I also tried reading from the source AVP backwards, as opposed to putting them in the destination AVP backwards as I do now, but there is no way to indicate the last index of an AVP. The common method of using -1 as the index does not work with AVPs. Any help would be appreciated. [1]: http://www.opensips.org/html/docs/modules/1.11.x/avpops.html#idp5675600 Thanks, Ben Newlin
