Sporadic E120171: Error running context: An error occurred during SSL communication

Hello!

Our svn server is hosted on a virtual server managed by some subcontractor. (Redhead enterprise linux, AFAIK).
When committing, we get too often the following errors.

In tortoise SVN en example message is:
"Command: Commit
Error: Übertragen schlug fehl (Details folgen):
Error: Fehler beim Ausführen des Kontextes: An error occurred during SSL communication
Completed!"

On the command line it looks like
D:\PRJ\DPS\bin>svn commit -m "CTRL_SH ignorieren" eventmemory.py
Sending eventmemory.py
svn: E120171: Commit failed (details follow):
svn: E120171: Error running context: An error occurred during SSL communication

There are some variants of these messages, obviously at different stages of the process.

As far as I know a restart of the apache web server does help, but after a few hours of use
these errors come back.
It feels like some resource is not properly freed, and when the server runs out of <i would like to know what>,
this error comes. Sometimes it helps to wait for 15 minutes and retry.

Who can tell me, what this message means and what to do about it?
What would I need to tell the server admins?

Mit freundlichen Grüßen
