Solaris 10 U2 svn export hangs

From: Fletcher Cocquyt <fcocquyt_at_stanford.edu>
Date: 2006-08-07 23:11:40 CEST

I have a solaris 10 x86 update 2 apache server that is hanging on svn exports -
 below is the pstack output during the hang (it usually hangs until I kill it)

There was a December 2005 thread with the same topic - but no resolution was
posted - anyone else seen this?

Currently I'm investigating on the dav modules -mt compile options (a sun
engineer mentioned this could be a cause)

Thanks,
Fletcher.
