do you have the same problem with lucene?

I collected a strace on the dovecot process during indexing:

Re: Dovecot 2.3.7.2 lucene segfault and coredump

Dovecot mailing list

Hi,

i have find other information of the coredump.

My mail_plugin is:
mail_plugins = quota fts fts_lucene mail_log notify virtual

When I using quota and fts_lucene the coredump is generated.
If i use only the quota plugin or fts_lucene plugin, lmtp store work correctly.

Have you an ideas?

Hi,

I have other information.

I analyzed the core dump:

Can you issue GDB command `bt full` at this point?
