Re: SVN issue :: _dl_close: Assertion :: HTTPS :: help!

Still having this issue. Happens with Apache 2.0.52 + Svn 1.1.3 and 2.0.53 + SVN 1.1.4.

I have managed to isolate the issue to SVN with Authentication so far. If mod_auth_pam is disabled then we can access repos fine. if Mod_auth_pam is enabled with 2.0.53 then error as below resurfaces. What we have noticed, is SVN client (SVN 1.1.4 or 1.1.3 or Tsvn 1.1.4) probbaly opens lot of SSL connections, and floods with auth requests. I am not sure, if its by design or its a bug, as i have hit the max in my understanding of things!

I have other websites such as viewcvs and websvn configured on the same server using same Mod_auth_pam schema, and it all works fine. no errors what so ever. http or https access doesnt seem to make any differnece either!

I have tested in across 4 different servers, and i have been able to reproduce above in all cases. We do need authenticated access in our setup, and, we have fairly large subversion user base, hence i am now kinda stuffed as how to get my users to work! any help much appreciated?

apache2.prefork: dl-close.c:365: _dl_close: Assertion `imap->l_type == lt_loaded || imap->l_opencount > 0' failed.

many thanks

  We had subversion 1.1.3 working fine on our Gentoo server for a while. A kernel upgrade required a reboot, and since then its stopped working. Reverting back to older kernel hasnt been any help either.

  Apache error logs show

  This happens on commands such as "svn update" or svn checkout etc. SVN fails saying

  svn: REPORT request failed on '/testing/!svn/vcc/default'
  svn: REPORT of '/testing/!svn/vcc/default': Could not read chunk delimiter: Secure connection truncated (https://svn.example.com)

  however, i am able to view the repo fine using webSVN. I have verified the repos using "svnadmin verify" they all come clean.

  on repeated 'svn update', it seems that the error typically happens around 9th or 10th file. but at times it has also happened just on 2nd or 3rd file.

  Server is running Gentoo, with kernel 2.6.11-r5. With Hardened flag set for GCC, and glibc etc. emerge info says

  Upgrading to Svn 1.1.4 hasnt been much help either. same errors persist.
  At this point, server and client, both are running Subversion 1.1.4. Same error occurs even when using tsvn client. Problem only occurs while accessing using SVN client. Its all fine, if i brows the repo directly using say Firefox. I have tested it with from client on linux as well as windows xp.

  I couldnt find much help on the net. Any help is much appreciated, i m lost as whats causing this error.

  many thanks,
