Crontab não disparando processos

mvitor · 20 de Maio de 2008, 09:30

Olá a toda comunidade. Tenho uma máquina com ubuntu instalado com kernel versão 2.6.18-5-686.
Tenho tido alguns problemas relacionados ao meu crontab. Tenho alguns processos que são disparados durante a madrugada, e em alguns dias estes processos são disparados normalmente, outros não. O meu crontab está agendado da seguinte maneira:

00 01 * * * /usr/bin/perl /home/spider/scap/scap.pl -r 79b
15 01 * * * /usr/bin/perl /home/spider/scap/scap.pl -r 32
00 02 * * * /usr/bin/perl /home/spider/scap/scap.pl -r 137b
30 02 * * * /usr/bin/perl /home/spider/scap/scap.pl -r 35b
00 03 * * * /usr/bin/perl /home/spider/scap/scap.pl -r 27
30 04 * * * /usr/bin/perl /home/spider/scap/scap.pl -r 525b
00 05 * * * /usr/bin/perl /home/spider/scap/scap.pl -r 555
00 05 * * * /usr/bin/perl /home/spider/scap/scap.pl -r 120b

Não sei porquê motivos os processos agendados entre 01:00 e 03:00 hrs não tem sido disparados, olhando o /var/log/syslog:

Alguém faz idéia do que pode estar acontencendo ? Estouro de memória ?
Agradeço por qualquer dica e avanços
