Temporary workaround to resolve this: I have a cron running these maintenance tasks but missing in between though. Need a permanent fix.

  1. Run svnadmin pack <REPO_PATH>
  2. Run chown -R scm:scm <REPO_PATH>

Looks like related to this issue:

Thank you Girish we will have a look at it.

This could take some time beacuse you already found a workaround for you. However we take it seriously.

The svnadmin pack <REPO> has less effect as SCM-Manager is working through the SVNKit and its cache/indexing still complaining that the latest REVISION is not yet packed.
SO both are working independently and is expected. The question is how do we resolve the delay in PACKING and/or refreshing the cache/indexes to be ready within the expectations?

1) I would run svnadmin pack <myrepo> and its complete quickly
RESULT: 107590

2) I would run YOUNGEST_REV=$(svnlook youngest myrepo) && svnadmin verify <myrepo> -r${YOUNGEST_REV}
RESULT:
* Verifying repository metadata ...
* Verified revision 107590.

All the above steps would take around 15-to-20 seconds.

3) Then I try running the CI builds which would take another 10-15 seconds to request SVN PROPS with the server through HTTPS

So over all 50 seconds to 60 seconds is the time interval between the COMMIT and NEXT REQUEST.

But it seems like insufficient time for the SCM-Manager to manage the POST COMMIT actions like, CACHE, PACKING, INDEXING and BE-READY.

This is a serious concern I am facing and I am helpless right now.

1) Is there a way we can fine tune the SCM-Manager performance by changing the workers count?
2) What else could solve this bottleneck?

The situation is growing beyond control.

The SVN repository becoming corrupt frequently and I am spending sleepless nights.

Hey Girish,

currently I can only give you some wild guesses and ask for more information…

  • Did you stumble about an error which mentioned malformed header in revision file?
  • Could it be that your infrastructure (reverse proxy, firewall) blocks any particular svn requests? Since each commit can consist of many requests I think this could create corrupt states.
  • Since when did this behavior occur and is only one repository affected?
  • As always: Is it possible that you provide an example repository so we can debug into it?

BR, Eduard
