Sleep command did not worked
Hi All,
We have a process which is running for last 2 years well and good in production. But suddenly yesterday there was issue we faced in the process.
The actual process is what it does like below.
1. Receive the files in NAS directory(N/w attached storage).
2. Trigger the process(some.ksh script) one for each file in the NAS directory in gap of 1 second, this is in for do - done loop.
This is running well and good till yesterday but suddenly there were 3 parallel process triggered for 2 files in NAS directory at same time (For ex: 11:30:10 AM). So initial analysis say there is nothing wrong in code which was actually fine but some how the sleep command was not worked.
Is there any thing behind which makes sleep command not to work?
Any comments suggestions will be helpful.
I am using AIX 6.0 version of UNIX server.
Thanks.

GONG(1) General Commands Manual GONG(1)
NAME
gong - evaluate process performance
SYNOPSIS
gong [-f] [-a] process-id
DESCRIPTION
Gong is used to evaluate the performance of a process that is in execution.
The process-id is the process number of the process whose performance is to be evaluated. The evaluation is performed by a set of three
``panelist'' routines, each of which analyzes one aspect (time, space, and tonality) of the performance of the process. If any of these
routines is not amused by the performance, the process being analyzed is sent the gong(2) signal. In addition, the process-id of the eval-
uated process is written on the standard gong, for possible future corrective action. (It is suggested that the standard gong be an audi-
ble alarm for proper effect.) It is expected that after being gong(2)ed, the process will promptly commit suicide.
The -f keyletter argument indicates that gong is to invoke flog(1) with the unmerciful argument if the process does not respond to
gong(2)ing. In the absence of this argument, the process is continuously gong(2)ed, which may lead to the process becoming a deaf zombie.
The -a keyletter argument indicates that if all three of the panelist routines gong(2) a process, the process should be unmercifully
flog(1)ged whether or not the -f keyletter is supplied.
FILES
/dev/ding.dong is the standard gong.
SEE ALSO
On the Applicability of Gonging to the Performance and Merit Review Process, Journal of Irreproducible Results, vol. 263, issue 19, pp.
253-307.
BUGS
If the named process does not exist, it is possible that gong will attempt an evaluation of itself, which may lead to a condition known as
compounded double ringing (see echo(1)). Therefore, it is recommended that gong be used with extreme care.
