errno=12 Not enough space

xinm — Wed, 27 Feb 2008 07:48:52 GMT

Dear friends:
When I run a C++ program ,it happens errors at“opendir()” function:
Errno=12, strerror(errno):Not enough space.

Then I check “/usr/include/sys/errno.h”:
#define ENOMEM 12 /* Not enough core */

MY Program’s Environment:
>>machine : ia64 hp server rx4640
Memory = 16371 MB (15.987305 GB)

>>OS info:
sysname = HP-UX
release = B.11.23

Hi,

Do you see any error messages in your syslog, something like could not fork or no buffer space?
What's the output of the following:
- vmstat 5 5
- sar -v 2 10
- swapinfo -tam

Goodluck
Darrel

The first thing you should do is read the man page under opendir(3). ENOMEM points to malloc(3).
As Volkmar said, your maxdsiz is probably too low.
