Comment (by franveux):

 It looks that the problem occurs when varnish is increasing the number of
 thread, while not been on a peak of request nor trafic.

 The following ugly code permits to avoid child crashes with no others
 troubles at this time:

 In cache/cache_busyobj.c just before line 171:

 if (bo == NULL) { // FVEMODIF avoid assert's child crash !!!
   syslog(LOG_NOTICE, "FVEMODIF: assert bo == null avoid crash...");
