Some things of note: * I'm using NFSv4 * There is a single client of this NFS share, which is an Ubuntu Linux clie= nt * This worked without stability issues in 13.x-RELEASE and 14.x-RELEASE pri= or to upgrading to 15.0-RELEASE I first tried the patch in a similar bug here with no change in behavior: https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D292884 However, after applying the 3 patches from this bug (in addition to the pat= ch in the bug linked above) I've now had 48h of stability for the first time s= ince updating to 15.0-RELEASE. Let me know if there is any additional information I can provide and thanks= for the fix! --=20 You are receiving this mail because: You are the assignee for the bug.=
