Smsd itself does not contain this kind of error message, it must come from the OS. I do not know what causes this error and how to fix it. Smsd has been working under Windows Server 2003, which means that probably you have something wrong in your system. Perhaps re-installing Cygwin helps.

Thanks Keke. I try to reinstall Cygwin.

I've found:

extras.c

int my_system(char *command, char *info)
{
int pid;
int status;
time_t start_time;

start_time = time(0);
#ifdef DEBUGMSG
printf("!! my_system(%s, %s)\n", command, info);
#endif
writelogfile0(LOG_DEBUG, 0, tb_sprintf("Running %s: %s", info, command));

pid = fork();
if (pid == -1)
{
writelogfile0(LOG_CRIT, 0, tb_sprintf("Fatal error: fork failed."));
return -1;
}

...

Oops :oops: , the message comes from the smsd...

But still, fork was initially worked and now child process cannot create another child process.

You could try to change the line to:

writelogfile0(LOG_CRIT, 0, tb_sprintf("Fatal error: fork failed. %i, %s", errno, strerror(errno)));

After recompiling you should see the error number and explanation in the log.

Is this problem still active?

The new version 3.1.12 has this change in the code, error number and explanation is shown, but there is no any other change to the fork() call.

It may be important to know in which place your system gives this error. In the smsd.log, is it right after smsd mainprocess was started, or is it later?
