I see that on spb-avtovo fs_server constantly fails in tests.
On Solaris, test show lots of orphaned fs_server processes.
There are also some core files, but with stripped binary they don't help a lot.
While trying to reproduce something I found that fs_server, I managed to reproduce the seg fault when exiting:
t@1 (l@1) terminated by signal SEGV (no mapping at the fault address)
0xffff80ffbf584a11: t_splay+0x0011: movq 0x0000000000000010(%rdx),%rsi
Current function is flush_impl

The regression was caused by fixes of static code checks (I would say, rather false positives). Should be fixed by change sets 1197667808c9, e85664e4f8e3 on enum.
Integrated into 'main-silver', will be available in build *201704110002* on http://bits.netbeans.org/dev/nightly/ (upload may still be in progress)
