c linux gcc ld dlsym
I want to link to a shared lib in C. (on Linux)I want to suppress or handle the:”error while loading shared libraries: libxxxx.so: cannot open shared object file: No such file or directory”and continue loading linking to next lib that might resolve the left unresolved symbols.I guess gcc/ld/dlsym options should be used but can not manage to understand how…Does anyone have a clue?

apache2 php memcache segfault
Three Apache2 web servers running a PHP 5.2.3 web site. We’re using Memcache to cache rendered pages but also as the storage engine of the PHP Sessions.At peak traffic times we’re getting Apache segmentation faults on all three web servers and all HTTPD child processes segfault. My gut tells me that the increased Memcache traffic is stopping PHP sessions from being created or cleaned up and thus the processes die. Is it possible for someone to confirm that from the following? :#0 _zend_mm_fr
