Same issue here.
I'm on centos with RB 1.5.
My source files can be as big as 20Mb which I didn't really expect to
be an issue. turns out viewDiff can take several minutes.

but performance aside I think I'm looking at some memory leakage.

after running it for a few days while no user is connected running

ps -eo pmem,pcpu,rss,vsize,args | sort -k 1 -r | less

is giving me

--------------------------------

restarting apache the top memory usage goes back to being memcahed
while apache moves to 2nd place with
0.2  1.2  5680  11780 /usr/sbin/apache2 -D DEFAULT_VHOST -D INFO -D
SSL -D SSL_DEFAULT_VHOST -D LANGUAGE -D PYTHON -d /usr/lib/apache2 -f /
etc/apache2/httpd.conf -k start

I'm going to configure apache so that each process is restarted after
just a few requests as a short term workaround.

can anyone help me out identify where the issue is?

TIA
