[ast-developers] ksh93-Scriptdaemon terminates unexpectedly

I run a ksh93-Daemon (with 'nohup ... &') and the daemon-process terminates unexpectedly and sporadically.

The last command executed:
print "$(date '+%d.%m.%Y %H-%M-%S') - go: $transferid1 check if lock file still active at $go" >> $CFOG

-> The date-command (GNU coreutils 8.4) caused the abort.

Does anyone have an idea?

Thanks,
Dirk

I don't know the cause of the abort, but have you tried
using printf to format the date instead? It's built into ksh93 so
there won't be any fork required and hopefully won't crash:

Use either:

print "$(printf '%(%d.%m.%Y %H-%M-%S)T\n') - go: $transferid1 check
if lock file still active at $go"

or

printf "%(%d.%m.%Y %H-%M-%S)T - %s\n" now "go: $transferid1 check if
lock file still active at $go\n"

I run a ksh93-Daemon (with ?nohup ? &?) and the daemon-process terminates
unexpectedly and sporadically.
print "$(date '+%d.%m.%Y %H-%M-%S') - go: $transferid1 check if lock file
still active at $go" >> $CFOG
