dovecot - Jun 2017 - updated to dove 2.30.1 and still the same error ....

Well.. updated to 2.30.1 hoping it would fix this mysterious seg fault
... ,but nope ... 

auth: Fatal: master: service(auth): child 14502 killed with signal 11
(core dumped) 

the core dump shows 

gdb) bt #0 0x00007f7ff4a06bee in ?? () 

#1 0x00007f7ff74a4f44 in io_loop_handle_remove () from
/usr/local/lib/dovecot/libdovecot.so.0 

#2 0x00007f7ff74a3765 in io_remove_full () from
/usr/local/lib/dovecot/libdovecot.so.0 

#3 0x00007f7ff7438b62 in master_service_deinit () from
/usr/local/lib/dovecot/libdovecot.so.0 

#4 0x00000000004307ef in main () 

no symbols are available as this is a pkg install.... so whats next?
time to dump dovecot after 

running it for 10 years? 

Can't believe no one else is seeing this .... 

the symtoms are 

dovecot starts up fine 

when a client connects, they authorize just fine and download email ....


about a minute later the auth process crashes and the entire process
starts over .... 

so how do you trouble shoot this ... it sounds like a coding issue some
place .... 

anyone ?

can you try 

https://lists.freebsd.org/pipermail/freebsd-ports/2009-November/057974.html

to have debug symbols?
