The servers are setup so that<br>only one is receiving any traffic other than replication at any time. The one that's only receiving replications is the<br>one that's failing.<br><br>I've tried deleting the user's home on the receiving server, but it still crashes during the sync. Oddly, the user's<br>home is 7.4G on the sending server, but ends up at 42G on the receiving side, even after deleting and trying a fresh sync.<br><br>The mailbox implicated in the backtrace ("Spam") does have a very large number of messages in it.<br>On sender:<br>Spam messages=1217764 recent=0 uidnext=1218103 uidvalidity=1379509105 unseen=16 highestmodseq=744588 vsize=34468460093<br>guid=090ed93a7a055559abf10200fdf6807a firstsaved=1498744186<br>On receiver:<br>Spam messages=1217766 recent=352 uidnext=1218105 uidvalidity=1379509105 unseen=16 highestmodseq=744589 vsize=34468496809<br>guid=090ed93a7a055559abf10200fdf6807a firstsaved=1519396172<br><br>Feb 23 14:57:20 dovecot: dsync-local(bgeels): Warning: fscking index file<br>/gnoc/mail/home/bgeels/mail/storage/dovecot.map.index<br>Feb 23 14:57:20 dovecot: dsync-local(bgeels): Warning: mdbox /gnoc/mail/home/bgeels/mail/storage: rebuilding indexes<br>Feb 23 14:57:33 dovecot: dsync-local(bgeels): Panic: file mail-index-util.c: line 10 (mail_index_uint32_to_offset):<br>assertion failed: (offset < 0x40000000)<br>Feb 23 14:57:33 dovecot: dsync-local(bgeels): Error: Raw backtrace: /usr/lib64/dovecot/libdovecot.so.0(+0x9f3de)<br>[0x7feb584143de] -> /usr/lib64/dovecot/libdovecot.so.0(+0x9f4be) [0x7feb584144be] -><br>/usr/lib64/dovecot/libdovecot.so.0(i_fatal+0) [0x7feb583a577c] -><br>/usr/lib64/dovecot/libdovecot-storage.so.0(mail_index_uint32_to_offset+0xa0) [0x7feb587906d0] -><br>/usr/lib64/dovecot/libdovecot-storage.so.0(mail_cache_compress+0x854) [0x7feb58774f34] -><br>/usr/lib64/dovecot/libdovecot-storage.so.0(mail_index_sync_commit+0x25f) [0x7feb587884ff] -><br>/usr/lib64/dovecot/libdovecot-storage.so.0(mdbox_storage_rebuild_in_context+0x10de) [0x7feb5870b3ae] -><br>/usr/lib64/dovecot/libdovecot-storage.so.0(mdbox_sync_begin+0x858) [0x7feb5870ccd8] -><br>/usr/lib64/dovecot/libdovecot-storage.so.0(mdbox_sync+0x4c) [0x7feb5870ce7c] -><br>/usr/lib64/dovecot/libdovecot-storage.so.0(mdbox_storage_sync_init+0x4b) [0x7feb5870cf3b] -><br>/usr/lib64/dovecot/libdovecot-storage.so.0(mailbox_sync_init+0x44) [0x7feb586f2834] -><br>/usr/lib64/dovecot/libdovecot-storage.so.0(mailbox_sync+0x37) [0x7feb586f28d7] -><br>dovecot/doveadm-server(dsync_mailbox_import_deinit+0x475) [0x445495] -> dovecot/doveadm-server() [0x43edc0] -><br>dovecot/doveadm-server(dsync_brain_sync_mails+0x743) [0x43f653] -> dovecot/doveadm-server(dsync_brain_run+0x541)<br>[0x43acf1] -> dovecot/doveadm-server() [0x43b070] -> dovecot/doveadm-server() [0x44fe5f] -><br>/usr/lib64/dovecot/libdovecot.so.0(io_loop_call_io+0x52) [0x7feb58429cd2] -><br>/usr/lib64/dovecot/libdovecot.so.0(io_loop_handler_run_internal+0x10f) [0x7feb5842b3bf] -><br>/usr/lib64/dovecot/libdovecot.so.0(io_loop_handler_run+0x3c) [0x7feb58429d6c] -><br>/usr/lib64/dovecot/libdovecot.so.0(io_loop_run+0x38) [0x7feb58429f28] -> dovecot/doveadm-server() [0x4209c5] -><br>dovecot/doveadm-server() [0x422df6] -> dovecot/doveadm-server() [0x4377f4] -><br>/usr/lib64/dovecot/libdovecot.so.0(io_loop_call_io+0x52) [0x7feb58429cd2] -><br>/usr/lib64/dovecot/libdovecot.so.0(io_loop_handler_run_internal+0x10f) [0x7feb5842b3bf] -><br>/usr/lib64/dovecot/libdovecot.so.0(io_loop_handler_run+0x3c) [0x7feb58429d6c]<br>Feb 23 14:57:33 dsync-local(bgeels): Fatal: master: service(doveadm): child 82098 killed with signal 6 (core dumped)<br><br>I've attached the output of `doveconf -n` and the full backtrace from a core dump.<br><br>Dovecot 2.2.33.2 (GhettoForge package)<br>CentOS 7 x86_64<br>XFS, no NFS.<br><br><br>-- Ian<br></body></html>
