[Bro] Manager swapping..

[Hovsep Levi]

Try disabling the SSL/TLS cert verification.  I'm not sure why but
that helped, without it the manager would slowly climb to massive
memory usage.  Now it works fine for one or two weeks before
unexpectedly using all memory.

#@load protocols/ssl/validate-certs

Good:

Name         Type    Host             Pid     Proc    VSize  Rss  Cpu   Cmd
logger-1     logger  10.1.1.1   6241    parent  701M   163M  20%  bro
logger-1     logger  10.1.1.1   6261    child   458M    69M   3%  bro
manager      manager 10.1.1.1   6345    child   510M   377M 100%  bro
manager      manager 10.1.1.1   6292    parent  890M   804M  24%  bro
