Can everybody help me to find a problem?
Sorry for my English.

Reboot everynight when run freebsd statistic generate.
Only on i386 platforms.

Problem very strange.
Maybe it's NOT a problem BOINC client.

If everyday reboot these computer's or just stop program (/usr/local/etc/rc.d/boinc-client stop) kernel panic is not happened.

On amd64 problem is not persist.
On other i386 computer witch 2Gb memory problem is persist too.

boinc-client-7.2.33_6 installed from ports.

These i386 computers visible on statistic site:
