Introduction to Linux - A Hands on Guide This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter. For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

Recently we have started getting the following errors in the cluster manager logfile on 1 of the nodes : >ERROR: ThreadSpawn: pthread_create returned an error. 12 12 804eaf0, tid = CMConnectListerner:-1257751632 file = unixinc.c, line = 537 {Tue Mar 29 14:22:12 2005 } >WARNING: ThreadSpawn : Retrying pthread_create..., tid = CMConnectListerner:-1257751632 file = unixinc.c, line = 538 {Tue Mar 29 14:22:12 2005 } >ERROR: ThreadSpawn: pthread_create returned an error. 12 12 804eaf0, tid = CMConnectList
in the non-detached mode, and the limited available memory in some system stack is consumed. At that point no new threads can be created in non-detached mode until those threads are detached/killed, or the parent process(es) killed and restarted. Solution: create the threads in the detached state with the pthread_attr_setdetachstate call, e.g.; pthread_attr_init http://www.linuxquestions.org/questions/linux-software-2/pthread_create-returned-an-error-12-12-a-307239/ (&id_attr); pthread_attr_setdetachstate(&id_attr, PTHREAD_CREATE_DETACHED); pthread_create( , &id_attr, , ); unless you really need the threads in the joinable (non-detached) state, in which case you will have a fixed upper limit to the number of joinable threads active at any one time. In the 2.4 kernels https://www.parkes.atnf.csiro.au/observing/documentation/computing_notes/linux_threads.html I've examined this limit appears to be 256 threads for each parent process(?). Some of this is documented in the man help for pthread_attr_init. However the man help for pthread_create makes no mention of the ENOMEM return and what it means, which is rather confusing. In the Linux 2.2 kernels I've examined the behaviour is slightly different. The system default for the maximum joinable threads alive at any one time seems to be 1024 (rather than 256), and pthread_create returns an error code 11 EAGAIN, and a global errno value of 4 ("Interrupted system call"). The solution is the same as for 2.4: if your process creates lots of threads, make them detached or manage carefully their maximum instantaneous population.
