[Zeek] tcmalloc large alloc

[Rogers, Zach]

Hello,

We have been seeing some crash reports on some of our nodes, regarding a tcmalloc error. I was wondering if anyone else has seen this before and if anyone has any suggestions on what the cause might be. We are running Zeek 2.6. Here is an example stderr.log output from one of these crashes:
