We are also getting similar errors in stderr.log, as follows:

2013-08-21 19:03:42.397 [STDERR] sh: host: command not found
2013-08-21 19:03:42.399 [STDERR] sh: host: command not found
2013-08-21 19:04:10.003 [STDERR] Cgid: Child process with pid: 244566 was killed by signal: 15, core dump: 0

2013-08-21 19:04:12.004 [STDERR] Cgid: Child process with pid: 244577 was killed by signal: 15, core dump: 0

stderr log is the output from processes writing to STDERR.
The "ping" and "host" error are from third party CGI or something.

the log like "Child process with pid: 244566 was killed by signal: 15, core dump: 0" is normal, just an idle external app being stopped with SIGTERM. core dump: 0 means no core dump, if a process crashes, core dump will be "1", signal is "11" or "7".
So, those messages is normal, does not indicate any problem.

Thanks for the info.

What about the stderr errors regarding PHP extensions and ionCube:

Are those also normal and can be safely ignored?
