Segfault

Today i got this warning ? Anyone can explain what it is
Apr 26 21:47:12 servername kernel: php-cgi[18550]: segfault at 00007fff57408218 rip 00000000005ed78a rsp 00007fff57408200 error 6

 

Did you see this only once, or again and again?

 

Got the error 2 times, havent been there since.

 

If it happens only sporadically, I wouldn't worry about it too much.

 

Just poorly written code by the web developers (since it said cgi I assume the warning came from accessing a web page.) They probably didn't pay attention to memory allocation or something because it probably was given a pointer to memory that it had no right to access.
