http://bugzilla.novell.com/show_bug.cgi?id=557636 http://bugzilla.novell.com/show_bug.cgi?id=557636#c7 --- Comment #7 from mandy wu 2010-08-16 06:50:45 UTC --- Should we do a repackage to resolve these two memory leaks as well? As I have observed, these memory leaks would definitely cause "Out of Memory" error after running 2 mins. It means if customers have any while loop in their code, the shipped perl could not be even used. -- Configure bugmail: http://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
