tracsvn updates and high cpu utilization

[robe]

Seems that tracsvn cpu went to 100% for the past 2 hours according to monitor charts. Most of it was apache. At anyrate to rule out corrupt memory etc, I took the time to run patch updates and restart.

Need to get 14.7 MB/19.5 MB of archives.
After this operation, 10.9 MB of additional disk space will be used.

At some point we will need to upgrade to apache 2.4 but I think a lot of config changes need to be made to make it compatible so will save that for another data.
