Hello, Could use some help on this one. The newest Thunderbird 45.7.0 on Mac OS Sierra 10.12.3 is giving EXC_BAD_ACCESS (SIGSEGV) errors (aka. the thing you are trying to reach has moved errors) from NFS mounted home directories. Every time I try to edit a draft Thunderbird crashes. Same issue if the drafts folder is local or on the imap server. Looks like some of the backend files dealing with NFS mounted accounts has been moved or changed. From a local account Thunderbird works fine, but the minute I switch to mounted home directory account, even if I am pointing to the exact same profile that was working earlier, I start getting the following errors: Exception Type: EXC_BAD_ACCESS (SIGSEGV) Exception Codes: KERN_INVALID_ADDRESS at 0x0000000000000018 Exception Note: EXC_CORPSE_NOTIFY Termination Signal: Segmentation fault: 11 Termination Reason: Namespace SIGNAL, Code 0xb Terminating Process: exc handler [0] Did some testing, affects all the recent versions of Thunderbird using Sierra 10.12.3 I have to revert back to 10.12.1 or earlier for any version of Thunderbird to work consistently from a NFS mounted home directory. Best guess since I can move a profile from a mounted home directory to a local account on the same computer, get Thunderbird not to crash when editing drafts, and move the profile back and get the same error, some sort of backend dealing with NFS mounts has changed and whatever is referencing the old backend needs to point to the new one. Since I already got asked in the forum why don't I use something other than NFS, its because my University's engineering department only supports NFS for moving home directories between multiple mac and linux computers. Some of the software I need only works from my mac this way due to licensing. I can use Thunderbird from a local account, but it means I have to switch accounts every time I want to answer my mail, which is getting annoying really fast.
