Como creo ver son procesos que se ejecutan con cron (veo un Process cat por
ahi), despues de eso
y por todo el dia de ayer hasta que lo reinicie dicho script no anduvo , se
ejecutaba con el cron pero no procesaba nada,
todo lo demas si(web,mysql,postfix,proftpd..etc).
solo dicho script se colgo, pero no el cat, porque otros scripts lo usan y
andaban ok.
Rebootearon el server a la tarde  y salio andando y toco madera pero hasta
ahora no problem,
 pero que es esto?
Tengo un debian sarge :
Linux servernanuevoc 2.6.8-2-386 #1 Thu May 19 17:40:50 JST 2005 i686
GNU/Linux
en un Pentium IV 3.2 con 1 Gb RAM

Gracias
