Hello
I am using a Lua script the extracts and writes to disk files from a packet. When running in "realtime" everything goes smoothly but the memory usage keeps growing until we have to restart everithing. So all points to a memerory leak somehwere. We are tapping sigtran traffic. Runnning with Valgring as recommended here (http://wiki.wireshark.org/Development/Tips) I obtained this:
Invalid read of size 4

Should I assume that there is a leak in mtp3_addr_to_str_buf function?
Thanks
