Hey everyone, I am new to this list but I stumbled across an issue on a newly installed server that I can't figure out by myself.
Short factsheet: OS CentOS 5.4 fully updated Apache 2.2.3 SVN 1.6.9 (Binary package from your site) Neon 0.28.4 (Binary package from your site) The following symptoms happen whenever a user opens a connection to the SVN repositories: As soon as the connection is established and the user starts to check out a large repository (around 5 GB) I can see the memory usage VIRT of the apache process to go up each time the SVN descends into a new subdirectory. It looks like it's caching some information on the directory but it never frees it afterwards. RES also goes up but not as fast as VIRT. I dug around the web to find more details on what actually uses the memory. When doing a pmap -x <pid> of the apache process handling the SVN connection I am able to monitor the memory allocation of a [ anon ] Mapping constantly rise when recursing into directories. This also does not get cleared up afterwards. Monitoring the process in TOP showed the memory to increase for the process handling SVN from 203 MB VIRT and 10 MB RES up to 350 MB VIRT and 126 MB RES without cleaning up the memory when SVN closed the connection. I disabled most of the other mods running (including mod_authz_svn) and it still happens. I pinned it down to the recursing in directories by checking out the SVN on another machine over the 100 MBit connection. The faster the connection the easier it is to monitor since the recursion into directories happens faster too. I also had this issue when running SVN 1.6.6 that came with CentOS 5 hence I tried upgrading to SVN 1.6.9. I don't know what kind of information you need in order to help me but I will be able to give you anything you ask for. I attached some info output at the bottom of this mail. Thank you for this great program. I hope this is nothing serious and I don't need to worry about. If this is something that I need to worry about hopefully it's something fixable :) Cheers, Sebastian TOP output === PID User VIRT RES SWAP 16415 apache 337m 116m 221m /usr/sbin/httpd -DSSL -k start 16421 apache 309m 93m 216m /usr/sbin/httpd -DSSL -k start 16420 apache 212m 17m 194m /usr/sbin/httpd -DSSL -k start 16423 apache 207m 14m 193m /usr/sbin/httpd -DSSL -k start 16422 apache 206m 13m 193m /usr/sbin/httpd -DSSL -k start 16418 apache 205m 12m 193m /usr/sbin/httpd -DSSL -k start 15747 root 202m 10m 191m /usr/sbin/httpd -DSSL -k start 16417 apache 203m 10m 193m /usr/sbin/httpd -DSSL -k start 16416 apache 202m 9948 192m /usr/sbin/httpd -DSSL -k start 16424 apache 202m 9944 193m /usr/sbin/httpd -DSSL -k start 16419 apache 202m 9368 193m /usr/sbin/httpd -DSSL -k start === PMAP -x 16421 output === Address Kbytes RSS Anon Locked Mode Mapping 00002b8575f54000 308 -
