Re: Dovecot 2.3.7.2 lucene segfault and coredump

Hi,

I have other information.

I analyzed the core dump:

(gdb) core 22534 [New LWP 22534] Reading symbols from /usr/libexec/dovecot/doveadm-server...Reading symbols from /usr/lib/debug/usr/libexec/dovecot/doveadm-server.debug...done. done.

Br,

Hi,

do you have the same problem with lucene?

I collected a strace on the dovecot process during indexing:

All missing libs are in "/usr/lib64" and no to "/usr/lib64/dovecot"

Can you help me?
