this something to expected ?\r\n\r\nhttp://buildbot.zfsonlinux.org/builders/fedora-21-x86_64-builder/builds/869\r\n\r\n\r\nIt's probably only the buildbots doing \"their thing\" and erroneously

doesn't occur on all buildbots though - haven't managed to see a pattern yet - if there is any\r\n\r\nsince the buildbots only seem to produce meaningful results for this year, I couldn't see if this is a \"regression\" (if at all);\r\n\r\nalso zfsstress seems to be a test just recently introduced - so not sure how meaningful that observation is\r\n\r\n\r\nThanks\r\n\r\nedit:\r\n\r\ncounter-example\r\n\r\nhttp://buildbot.zfsonlinux.org/builders/ubuntu-13.10-amd64-builder/builds/2888\r\ndoesn't show any weird

Is this something to expected?\r\n\r\nYes, this is to be expected.  Nothing to see here.  The zfs-stress tests @nedbass put in place randomly generate file and path names which happen to look like gibberish.  This is a pretty recent addition to the tests which we originally put in place to run down #3195 and which was fixed by 58806b4cdc32e6f4e4a214cfba3b62a24efb34b7."}}
