Comment(by bdbaddog):
If I strace the process while it's pegging the cpu. It's reading from the
sqlite db file. Pretty much the whole time.
I ran an strace on buildbot. It bailed out when the file hit 2GB (it's a
32bit system).
1/2 of the lines in the strace log were reading from the sqlite datafile.
The buildbot master memory footprint was only 89MB, so it isn't swapping.
I believe it should be possible to log all the queries to get a handle on
what's happening based on : [http://stackoverflow.com/questions/1607368
/sql-query-logging-for-sqlite]
If I get a chance over the weekend I'll try to enable that.
Can you point me to the code where the sqlite connection is opened?
