------------------------------------------------------------------------ r47305 | gerald | 2013-01-26 12:12:52 -0800 (Sat, 26 Jan 2013) | 6 lines Changed paths: M /trunk-1.8/tools/fuzz-test.sh Instead of setting resource limits on the fuzz-test.sh process itself, set limits on the TShark subprocess. This should hopefully take care of the strange fuzz failures we've seen lately. Reduce the maximum CPU time to 5 minutes while we're at it. ------------------------------------------------------------------------ svn path=/trunk/; revision=47307
