[Bro] troubleshooting bro memory usage?

I *added* a ton of Reporter::warn messages. Before this, bro was issuing
one interesting error (see below), but I was basically adding lines like
"script <x> started with variables <y>", "script <x> finished", etc to
So, the log messages looked like:
0.000000 Reporter::WARNING making tempfile:
/opt/bro/share/bro/securityonion/./hostname.bro, line 40
0.000000 Reporter::WARNING wrote hostname to tempfile
/opt/bro/share/bro/securityonion/./hostname.bro, line 42
0.000000 Reporter::WARNING called event to add hostname
reader /opt/bro/share/bro/securityonion/./hostname.bro, line 44
0.000000 Reporter::WARNING hostname reader starting on file:
/opt/bro/share/bro/securityonion/./hostname.bro, line 28
1376401730.326379 Reporter::INFO processing suspended (empty)
1376401730.326379 Reporter::INFO processing continued (empty)
1376401730.370328 Reporter::INFO processing continued (empty)
What got me going this way was an error earlier that was:
0.000000 Reporter::WARNING Template value remaining in BPFConf
/opt/bro/share/bro/securityonion/./bpfconf.bro, line 99
which said to me that either the "hostname" or "interface" variable
hadn't been initialized in the bro setup.
