Any ideas?

I will try to get better dumps, but this is hard to reproduce atm, I will try to narrow it down or figure out how to trip it.

I do know the last thing I am calling is a server.reset() for webserver..

[tablatronix]

culprit seems to be
delete[]_currentHeaders;

[tablatronix]

dup #4350 ?

[tonton81]

really? core 2.1? can you try with a newer version ?:P

[tablatronix]

Its staging

@tablatronix sketch? Did you try latest git, i.e.: after #4365 ?
