I've never seen this problem with previous version, but i do some update in same time
kernel 3.11.7 + openafs 1.6.5.1 : no problem kernel 3.11.8 + openafs 1.6.6pre : problem I've test with tmpfs , --memory , and zfs cache. ( same issue with tmpfs and zfs , with --memory, sometime the copy of file is stopped and cache does not grow anymore ) for cache system. backing filesystem ( vicea ) is zfs. this problem appears to random way, it seems more frequents when i acces to afs mount , very soon after afsd is starting .
