+++ This bug was initially created as a clone of Bug #105616 +++ From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.4) Gecko/20030701 Description of problem: There are problems with cron not running jobs and/or not mailing the output to the user. If the program only has a little output, it is not mailed. In other circumstances, the job does not run at all unless one attaches to the process with strace. Using nss_ldap seems to exacerbate these issues, but the problem is intermittent and extremely hard to reproduce in the same way each time. Version-Release number of selected component (if applicable): How reproducible: Sometimes Steps to Reproduce: 1. define a cron job 'echo this is a test' 2. 3. Actual Results: output not mailed to user Expected Results: output should have been mailed Additional info: Here's a patch that fixes the issue: diff -uNr vixie-cron-3.0.1.orig/do_command.c vixie-cron-3.0.1/do_command.c --- vixie-cron-3.0.1.orig/do_command.c 2003-09-25 10:57:03.000000000 -0700 +++ vixie-cron-3.0.1/do_command.c 2003-09-25 10:57:37.000000000 -0700 @@ -161,7 +161,7 @@ /* fork again, this time so we can exec the user's command. */ - switch (vfork()) { + switch (fork()) { case -1: log_it("CRON",getpid(),"error","can't vfork"); exit(ERROR_EXIT); diff -uNr vixie-cron-3.0.1.orig/popen.c vixie-cron-3.0.1/popen.c --- vixie-cron-3.0.1.orig/popen.c 2003-09-25 10:57:02.000000000 -0700 +++ vixie-cron-3.0.1/popen.c 2003-09-25 10:57:53.000000000 -0700 @@ -94,7 +94,7 @@ #endif iop = NULL; - switch(pid = vfork()) { + switch(pid = fork()) { case -1: /* error */ (void)close(pdes[0]); (void)close(pdes[1]); -- Additional comment from jvdias on 2004-08-04 19:31 EST -- fixed in old vixie-cron-3.? and in latest vixie-cron-4.1-+.
