supervisor crashes xserve with malloc errors
« on: July 28, 2010, 05:24:11 PM »
. . . me again

About once a day our supervisor is crashing our main os x server.  I checked the logs and this is what I found in the supe.log ;

Code: [Select]
*** set a breakpoint in malloc_error_break to debug
terminate called after throwing an instance of 'std::bad_alloc'
  what():  St9bad_alloc
supervisor(2254) malloc: *** mmap(size=1595867136) failed (error code=12)
*** error: can't allocate region
*** set a breakpoint in malloc_error_break to debug
terminate called after throwing an instance of 'std::bad_alloc'
  what():  St9bad_alloc

. . . seems like some sort of memory error.  Could this be generated from bad memory modules in the server?

Hi R,

We've not seen this happen to others.
What version of the OS is this?

As you suspect, I also think it's likely a hardware issue.

The MacOS memory test is known to often "pass" bad memory.
Having said that, you could first try running the memory test in single-user
mode for a little more thorough RAM test. If it still doesn't catch an issue,
you may want to try a third-party memory testing app, such as "memtest"
http://www.memtestosx.org/ (I just checked, but they don't have a OSX 10.6
version, though).

Let us know how these tests go.
