The IPPortocolEndpoint and NetworkPort plugins collect raw network counters from /proc/net/dev. The string array allocated for these raw metrics is based on an ULL datatype size and not the maximum possible characters required to represent these numbers. Large counters result in a buffer overflow and generally a segfault.
