Hi all,

          Fedora-ds was down for some reason,

          And  I  got these logs:

 

 

[23/Dec/2010:18:59:32 +0200] - libdb: User-specified malloc function returned NULL

[23/Dec/2010:18:59:32 +0200] - id2entry error 12

The server has probably allocated all available virtual memory. To solve

this problem, make more virtual memory available to your server, or reduce

one or more of the following server configuration settings:

  nsslapd-cachesize        (Database Settings - Maximum entries in cache)

  nsslapd-cachememsize     (Database Settings - Memory available for cache)

  nsslapd-dbcachesize      (LDBM Plug-in Settings - Maximum cache size)

  nsslapd-import-cachesize (LDBM Plug-in Settings - Import cache size).

Can't recover; calling exit(1).

 

 

 

      It looks like no more available virtual memory to use, so should I set a lager nsslapd-dbcachesize?

      I don't know if it will down again, and please give me some advice . its important to me. Thanks a lot

What version of fedora-ds or 389-ds-base?
What platform?

This usually means you have run out of memory.  The usual thing is to reduce your cache sizes (as specified above).  Start with nsslapd-dbcachesize as the minimum.  Set nsslapd-cachememsize to be large enough to cache all of your entries, but no larger.
