fzzzz

We moved a big call center system (a NCR unix server and a connected tele switch) into a new server room. After 2 weeks someone called from the sales staff complaning that the system didnt deliver any phone calls to the sale people using it (around 100 persons). We tried to acces the server and it did look OK then we checked the admin console on the big tele switch and it said that it couldnt connect to the switch cards in the cabinet so we went down to the server room.. .. mmmmm... mmm..

We had placed the tele switch directly under a cooling machine that was water driven (you can se were im going with this.. Smilie

).

we hade around 5-6 liter of water in the tele switch cabinet... we even had water in the power supply that was mounted in the cabinet with no shielding cover! Smilie

the funny thing was that the admin console card was still working despite the fact that 6 liters of water hade gone trough the power suply Smilie

im just glad we didnt get electricuted Smilie

VERY EXPENSIVE MISTAKE !!!!!! the swtich was around 200K $...

pthread_self

PTHREAD_SELF(3) 					     Linux Programmer's Manual						   PTHREAD_SELF(3)

NAME

       pthread_self - obtain ID of the calling thread

SYNOPSIS

       #include <pthread.h>

       pthread_t pthread_self(void);

       Compile and link with -pthread.

DESCRIPTION

       The  pthread_self()  function returns the ID of the calling thread.  This is the same value that is returned in *thread in the pthread_cre-
       ate(3) call that created this thread.

RETURN VALUE

       This function always succeeds, returning the calling thread's ID.

ERRORS

       This function always succeeds.

CONFORMING TO

       POSIX.1-2001.

NOTES

       POSIX.1 allows an implementation wide freedom in choosing the type used to represent a thread ID; for example, representation using  either
       an  arithmetic  type  or  a structure is permitted.  Therefore, variables of type pthread_t can't portably be compared using the C equality
       operator (==); use pthread_equal(3) instead.

       Thread identifiers should be considered opaque: any attempt to use a thread ID other than in pthreads calls is nonportable and can lead	to
       unspecified results.

       Thread  IDs  are  only guaranteed to be unique within a process.  A thread ID may be reused after a terminated thread has been joined, or a
       detached thread has terminated.

       The thread ID returned by pthread_self() is not the same thing as the kernel thread ID returned by a call to gettid(2).
