[osol-discuss] libc thread failure: _thread_setschedparam_main() fails
I wrote a new memory allocation function to replace the glibc malloc() in solaris 10. It compiles well, but when I try to run it, I get the following message: *** libc thread failure: _thread_setschedparam_main() fails I've traced the program and found the error occurs at pthread_mutex_lock(). I don't know Do you have any experience or suggestion on solving this problem? Thank you in advance. -- This message posted from opensolaris.org ___ opensolaris-discuss mailing list opensolaris-discuss@opensolaris.org

Actually, I am writing a new spm_malloc() interface for some academic
research reason. The spm_malloc() is going to allocate a small on-chip
memory for multicore.
it looks like: void *spm_malloc(long bytes), I test the function in many
programs, it works ok.
In this example, the malloc() is called like this:
struct queue {
int head, tail;
void ** data;
int size;
int threads;
int end_count;
#ifdef PARALLEL
pthread_mutex_t mutex;
pthread_cond_t empty, full;
#endif //PARALLEL
};
struct queue *chunk_que;
chunk_que = spm_normal_malloc(sizeof(struct queue) * nqueues);
pthread_mutex_init(que-mutex, NULL);
pthread_mutex_lock(que-mutex); //The error occurs here!
...
Can you tell me how the malloc() function will do some relationship with the
pthread_mutex_lock() function? I think that is the point. Many thanks.

Re: [osol-discuss] eSATA works fine?
I always install GRUB on the Solaris partition, never on MBR - because if there is a problem with GRUB, it is just a matter of activating the Solaris partition. If I install GRUB on MBR and if there is a problem, I have to reinstall GRUB, fix the configuration file, etc - much more work. It is easier to just activate the Solaris partition. -- This message posted from opensolaris.org ___ opensolaris-discuss mailing list opensolaris-discuss@opensolaris.org

The confusing message is caused (in Solaris 10) by calling
pthread_mutex_lock() on an uninitialized mutex, due to
random garbage in the mutex.
Go check your test program. It is not doing what you think it is.
Check the return code from your call to pthread_mutex_init().
If you want more help, post a complete test program, not just
the snippets shown above.

[osol-discuss] machine drops off the network
Hi all, Things have been going pretty well with my home fileserver, but recently and I think increasingly, the system is dropping off the network for just long enough to disrupt connections. It only really happens when copying large amounts of data, for example an 8 gig folder of mixed file sizes. Client: Windows 7 x64 Server: zfs/cifs on SunOS exodus 5.11 snv_133 i86pc i386 i86pc Solaris I dont run any other client operating systems so I can't test with any others. In the middle of a copy (or right at the beginning, its random) i'll get a message saying the network path couldn't be found. After I convince windows to cancel and try to access the share myself, it's all fine. My NFS shares however are a bigger problem, I've never found NFS to be very tolerant of things like this and its causing some big headaches for me. I'm no expert in tracking down this kind of stuff so any pointers are much appreciated. Thanks Matt ___ opensolaris-discuss mailing list opensolaris-discuss@opensolaris.org

What model motherboard are you using? I suspect it's probably a nic driver issue. -- This message posted from opensolaris.org ___ opensolaris-discuss mailing list opensolaris-discuss@opensolaris.org

Go check your test program. It is not doing what you think it is. Check the return code from your call to pthread_mutex_init(). Also verify pthread_mutex_init() isn't being called more than once. ___ opensolaris-discuss mailing list opensolaris-discuss@opensolaris.org
